Tower of Saint Nicholas, Coca

Coca

The Tower of Saint Nicholas (Torre de San Nicolás) is a solitary brick tower standing on Plaza Cruz de los Caídos in the small town of Coca, in the province of Segovia, Castile and León. It is the only surviving piece of a former church that once carried the same name — the rest of the building came down at the end of the 17th century, leaving the tower as the last physical trace of a lost parish church. How old is the tower? Its exact construction date is unknown, but written records already mention it in 1247, making it one of the oldest surviving structures in Coca. Stylistically it belongs to the Gothic-Mudéjar tradition: according to historian Julio Valdeón Baruque, its overall form echoes the minaret-like tower of the Great Mosque of Córdoba, visible in the proportions of the shaft and in the way the brickwork is laid out. What does the tower look like up close? The tower rises on a roughly square plan and is built almost entirely from brick, arranged in patterns typical of Mudéjar craftsmanship. The lower section is decorated with blind arches — recessed niches shaped like arches but without any actual opening — while the level above switches to true, open arcades that let light through the walls. Near the top, in what used to be the bell stage, four pairs of window openings break up the mass of brick, giving the tower a pierced, lace-like silhouette that stands out against the flat landscape around Coca. What happened to the tower once the church was gone? Losing its original church did not mean the tower fell out of use. Over time it took on the roles of town bell tower, clock tower, and dovecote. This kind of afterlife is common for church towers in this part of Spain: once the main building collapsed or was demolished, a sturdy brick tower was often too solid — and too useful — to pull down as well. Is the tower a protected monument? Yes. On 3 June 1931 the tower was declared a historic-artistic monument and folded into Spain's National Artistic Heritage. Today it is listed as a Bien de Interés Cultural, in the Monument category, under heritage registry number RI-51-0000879. That status guarantees formal conservation protection even though the tower no longer serves any practical purpose. What else is worth seeing in Coca? Coca is also home to the Coca Castle (Castillo de Coca), one of Spain's best-known examples of Mudéjar military architecture, and to the church of Santa María la Mayor, built in the 16th century on the site of an earlier Romanesque church. Modest in size next to these landmarks, the Tower of Saint Nicholas still rounds out the picture as a reminder of how many parish churches the small town once had. Frequently Asked Questions How old is the Tower of Saint Nicholas in Coca? The exact build date is not recorded, but documents confirm it already existed in 1247, so it is at least several centuries old. Why is the tower still standing if the church collapsed? The Church of San Nicolás fell down at the end of the 17th century, but its solid brick tower survived and was later reused as a bell tower, a clock tower, and a dovecote. What architectural style is the tower built in? It follows the Gothic-Mudéjar style, built in brick, with details echoing the tower of the Great Mosque of Córdoba. Does the Tower of Saint Nicholas have heritage protection? Yes, it has been a historic-artistic monument since 1931 and is now registered as a Bien de Interés Cultural under the Monument category. What other sights are near the tower? Coca also has the Mudéjar Coca Castle and the 16th-century church of Santa María la Mayor, together forming a compact but rich cluster of monuments in the town.

Alconétar Bridge

Garrovillas de Alconétar

Alconétar Bridge Alconétar Bridge, sometimes referred to by its other name, Puente de Mantible, is a Roman segmental arch bridge standing in the municipality of Garrovillas de Alconétar, in the Extremadura region of Spain (Cáceres province). Evidence from its design points to a construction date in the opening decades of the 2nd century AD, and its flattened arches rank among the earliest known examples of this design used in Roman bridge engineering. Where is the bridge located? The bridge stands within the municipality of Garrovillas de Alconétar, in the province of Cáceres, in the Extremadura region of western Spain — an area regarded as one of the richest in Roman-era remains on the Iberian Peninsula. Its exact position corresponds to the coordinates 39.753838, -6.437345. Where does the name Puente de Mantible come from? Alongside its official name, Alconétar Bridge, the structure is also widely known as Puente de Mantible. Both names identify the same bridge and turn up interchangeably in references to this monument. When was the bridge built, and by whom? The design of the structure points to a construction date in the opening decades of the 2nd century AD, during the reign of Emperor Trajan or his successor Hadrian. Oversight of the works may have been provided by Apollodorus of Damascus, the most celebrated architect and engineer of that era, known for several other major Roman building projects of the period. His involvement at Alconétar, however, remains a plausible attribution rather than a documented certainty. What makes the bridge's construction remarkable? The bridge's most notable feature is its arch form: a flattened arch in which the ratio between span and rise reaches roughly 4 to 5 to 1. The higher this ratio, the greater the engineering challenge, since a flatter arch redistributes structural loads differently than a semicircular one and calls for more precise stonework and load calculation. Alconétar is regarded as one of the earliest known Roman bridges built with arches of this proportion, making it a notable reference point in the history of ancient bridge engineering. Why is it worth visiting? For anyone interested in Roman antiquity and the history of engineering, the bridge offers a rare chance to see an early example of a bold structural solution that would later be refined across centuries of European bridge building. It also gives visitors a reason to pair a trip through Extremadura — one of Spain's richest regions in Roman-era remains — with a stop at a lesser-known but historically significant site. Frequently Asked Questions Where exactly is Alconétar Bridge located? In the municipality of Garrovillas de Alconétar, Cáceres province, Extremadura region, at coordinates 39.753838, -6.437345. What is Puente de Mantible? It is the alternative, widely used name for the same Roman bridge — Alconétar Bridge and Puente de Mantible both refer to the same structure. When was the bridge built? Most likely in the opening decades of the 2nd century AD, during the reign of Emperor Trajan or Hadrian. Who designed the bridge? The exact designer is not confirmed, but Apollodorus of Damascus, the most prominent Roman architect of the period, is considered a possible contributor. What is special about the bridge's design? Its flattened arch, whose span-to-rise proportion sits at roughly 4 to 5 to 1 — one of the earliest known examples of this ratio in Roman bridge engineering.

Lo Molinot

Miravet

Lo Molinot is the ruin of an old water mill standing right on the bank of the Ebro river, within the municipality of Miravet, in the Ribera d'Ebre comarca of Tarragona province, Catalonia. It sits well away from the village's usual visitor routes, and today looks less like a former industrial building and more like a stretch of stone wall swallowed by the riverside rock. Where exactly is Lo Molinot located? The mill lies southwest of the centre of Miravet, along the path toward Xesa, on an outcrop known locally as Roca de Besaculs — right above the waters of the Ebro, the river that has shaped Miravet's entire history, from its medieval castle to its old river-trade routes. Getting to the mill itself takes some effort: the ground is uneven, and dense vegetation covers much of the remaining walls. What kind of mill was it, and how did it work? Lo Molinot was a hydraulic mill — a building that used the current of the Ebro to turn a millstone. It has a rectangular floor plan and was built of stone, likely bonded with lime mortar, a construction method typical of rural architecture in this region during the medieval period. One section of vaulting survives: a shallow, segmental arch through which water once flowed into the mill to drive its mechanism. That single arch is really what identifies the ruin as a mill today, since almost nothing else of the original structure remains intact. What condition is it in today? The mill is in poor condition. It has lost its roof and most of the upper sections of its walls, and the interior is now overgrown with thick vegetation, to the point that from a distance it barely reads as a man-made structure at all. What remains is essentially the one surviving arch and a handful of stone wall fragments — the rest collapsed over the decades once the mill stopped being used. Is Lo Molinot a protected heritage site? Yes. Despite its ruined state, it is listed in the Inventari del Patrimoni Arquitectònic de Catalunya (Catalonia's Inventory of Architectural Heritage) under catalogue number 39609, classified as an example of vernacular architecture — practical buildings raised without professional architects, following construction methods worked out locally. Being on the inventory, however, does not mean the mill has undergone any restoration; it remains an unsecured ruin. How do you get there, and can you visit? There is no signposted tourist route leading straight to the mill. Reaching it means walking the path toward Xesa, and the site itself has no facilities, markers, or paths laid out for visitors. Given the overgrown terrain and complete lack of infrastructure, some caution is worth taking, particularly in the warmer months when the vegetation is at its thickest. It's worth pairing a visit with Miravet's medieval castle, which overlooks the river from higher ground — seeing the two together makes it easier to understand why this stretch of the Ebro valley has drawn water-powered settlement for centuries. Frequently Asked Questions What is Lo Molinot? It's the ruin of a medieval water mill on the bank of the Ebro river, in the municipality of Miravet. Is the mill still in use? No. It is a ruin that has lost its roof; only wall fragments and a single arch, once used for the water inlet, survive. Is Lo Molinot a listed heritage site? Yes, it appears in Catalonia's Inventory of Architectural Heritage under number 39609, as an example of vernacular architecture. Is there an entrance fee? No, the site is open and unfenced, but it has no visitor infrastructure — no paths, signage, or safety measures. Where exactly should I look for it? Southwest of central Miravet, along the path to Xesa, on the Roca de Besaculs outcrop just above the Ebro.

Castle of Terrer

Terrer

The Castle of Terrer overlooks the small town of Terrer, set along the Jalón river valley in the province of Zaragoza, Aragon. Little remains of the original stronghold beyond scattered wall fragments, yet its story stretches back over a thousand years, to an era when this stretch of the Jalón valley marked the frontier between Muslim and Christian Iberia. Who built the castle, and when? The fortress was raised in the 9th century under the Banu Qasi, a powerful Muslim dynasty that held sway over the Upper March (Marca Superior), the buffer zone shielding Al-Andalus from Christian territories to the north. Terrer formed part of a defensive chain alongside the strongholds of Tudela and Borja, helping secure the Jalón and Ebro valleys against incursions from the north. What part did it play in the Reconquista? Terrer's name appears in the Cantar de Mio Cid, the great medieval Spanish epic. Rodrigo Díaz de Vivar, better known as El Cid, captured the castle in 1081 during his campaign through lands belonging to Zaragoza, taking nearby Bubierca, Ateca and Alcocer along the way. The fortress subsequently reverted to Muslim hands for a time. Its definitive conquest by Christian forces only came in 1122, under Alfonso I of Aragon, called El Batallador — two years after Zaragoza itself had fallen, in 1110. Why was Terrer important in the 14th century? The castle became the setting for a significant diplomatic moment during the War of the Two Pedros, the long conflict between the Crown of Aragon and the Kingdom of Castile. In 1361, its halls hosted the signing of the Peace of Terrer, a truce agreed between Pedro IV of Aragon and Pedro I of Castile, under which both sides committed to returning captured castles and releasing prisoners. The truce proved short-lived. By 1363, Pedro I's troops swept back through the Jalón and Jiloca valleys, devastating town after town. Terrer, unlike many of its neighbours, held out and was never taken. Pedro IV of Aragon rewarded this resistance by confirming and restoring the town's privileges. What survives at the site today? Very little of the original structure remains standing. What can still be seen are ruined stretches of wall built in adobe, or rammed earth — remnants that historians believe once formed part of a double defensive perimeter encircling the fortress. This makes the castle more of an archaeological ruin than a restored monument: a tangible trace of the site's long frontier history rather than an intact building. Where is Terrer, and how do you plan a visit? Terrer sits in the Jalón valley, close to Calatayud, one of the larger towns in this part of Zaragoza province. The wider area is dense with medieval military heritage — castles and defensive walls line the Jalón and Jiloca valleys — making it a rewarding stop for anyone tracing the history of the Reconquista and the old Christian-Muslim frontier. Frequently Asked Questions How old is the Castle of Terrer? The fortress dates back to the 9th century, giving it over a thousand years of history spanning both the Muslim and Christian periods. Can visitors explore the castle? The site today is essentially an archaeological ruin, best viewed from the surrounding area. Anyone planning a visit should check current access details with the local Terrer town council. What was the Peace of Terrer? It was a 1361 truce signed at the castle between Pedro IV of Aragon and Pedro I of Castile, marking a pause in the War of the Two Pedros and providing for the return of captured castles and prisoners. Why does the castle appear in the Cantar de Mio Cid? Because El Cid captured it in 1081 while campaigning through the lands of Zaragoza, an episode recorded in that medieval epic.

Tower of Ordás

Sorrios de Ordás

Tower of Ordás stands on a hillside above the valley of the River Luna, right where it meets the River Omaña, in the municipality of Santa María de Ordás, province of León, Castilla y León. It sits only a short distance from Sorrios, a small hamlet within the same municipality, and roughly 30 kilometres from the city of León. It is one of the better-preserved medieval defensive towers in the Omaña region. Where exactly is the tower located? The tower rises on high ground overlooking the village of Santa María de Ordás, right next to Sorrios. Its position was chosen deliberately: from here it commands the point where the Luna and Omaña river valleys converge, a spot that carried real strategic weight for controlling access into the interior of the region for centuries. Who built it, and why? The structure standing today dates from the 14th century and is attributed to Pedro Suárez de Quiñones, who held the office of adelantado mayor — the crown's chief administrator — for the Kingdom of León. It was raised over the remains of an earlier fortification of unknown origin, meaning the site had defensive use well before the 14th century. The tower formed part of a chain of towers and strongholds along the Omaña, Luna and Órbigo rivers, linked to the Quiñones family and the House of Luna, built to secure and control this stretch of territory. What does the tower look like? It is a cylindrical structure of stone and mortar, rising more than 20 metres. It has no crenellations at the top. Rows of putlog holes in the masonry indicate the tower originally had five floors. Inside, sections of a circular stone staircase that once connected those floors are still visible. The arrow slits are cut from dressed stone, and the window openings are framed with ashlar and small columns. A shared latrine drain served the first and fourth floors, while every level had its own chimney flue. Can visitors go inside? The grounds around the tower are open and free to visit at any time. Entry to the interior, however, requires prior arrangement with the town hall of Santa María de Ordás (tel. 987 590 076), since the building is municipal property and protected heritage — it is listed under a 1949 heritage decree and Spain's 1985 Historical Heritage Law. Is there a legend attached to the tower? Local tradition holds a grim family story: a young nobleman, Don Ares de Omaña, is said to have died here at the hands of his own uncle, Pedro Suárez de Quiñones. The tale is still told around Santa María de Ordás and often comes up on local history walks through the Omaña valley. Frequently Asked Questions How old is the Tower of Ordás? The current structure dates from the 14th century, though it was built on top of an earlier, unidentified fortification. Is the tower in good condition? It is partially ruined but has undergone restoration work and remains structurally stable; ownership rests with the municipality of Santa María de Ordás. How many floors did the tower originally have? Evidence in the stonework points to five original floors. How do you get to the Tower of Ordás? It lies about 30 km from León, in the municipality of Santa María de Ordás, next to the hamlet of Sorrios. Is a visit free? The exterior grounds are free to visit; going inside requires contacting the town hall in advance.

Castillo de Mondújar

Lecrín

Castillo de Mondújar is a late Nasrid-era fortress perched on the Castillejo hill above the village of Mondújar, within the municipality of Lecrín in Granada province, southern Spain. Sitting at roughly 879 metres above sea level near the A-44 motorway that links Granada with Motril, the site still preserves sections of its defensive walls, most visibly along the northern and eastern flanks. Where exactly is the castle located? The fortress occupies a commanding position above the Lecrín Valley, a corridor that historically connected the city of Granada with the Mediterranean coast and the Alpujarra mountains. From its hilltop, the site overlooks the surrounding ridges and the old trade route it was built to watch over. Who ordered its construction? The castle was commissioned by Abu l-Hasan Ali, better known as Muley Hacén, the penultimate sultan of the Nasrid Emirate of Granada, who ruled between 1464 and 1482. Gardens and orchards were laid out around the fortress for the royal family's leisure. When his son Boabdil rebelled against him in 1483, the deposed sultan withdrew to Mondújar, spending his final two years there until his death. Why is it also called the Castle of Zoraya? The fortress carries a second name, Castillo de Zoraya, after Isabel de Solís, known as Zoraya, Muley Hacén's wife. She was a Christian girl, only about 10 to 12 years old, captured during a Nasrid raid on Aguilar de la Frontera in the 1470s. She later converted and became the sultan's consort, and her name has stayed attached to the place where he spent his last years. What defensive role did the castle play? Castillo de Mondújar belonged to a defensive network protecting the Lecrín Valley, a system whose roots go back to the 9th century. Fortresses in this area regulated the movement of people and goods between Granada, Alhama, the coast and the Alpujarra, safeguarding one of the emirate's key strategic corridors. What happened after the Castilian conquest? Following the fall of Granada in 1492, the castle remained occupied for a time, but by 1555 records already describe it as abandoned and in ruins. Earlier, in late 1499, during the Morisco uprising, the Castilians lost nearly every stronghold in the Lecrín Valley — except this one. Castillo de Mondújar was held by Guiomar de Acuña, who defended it with only forty men along with a group of women and children. What remains to see today? The surviving structure shows an irregular, polygonal layout built in rubble masonry (mampostería). The best-preserved wall sections lie on the north and east sides, and they are what allow visitors today to trace the original outline of the fortification. Frequently Asked Questions Where is Castillo de Mondújar located? On the Castillejo hill above the village of Mondújar, in the municipality of Lecrín, Granada province, close to the A-44 motorway. Who built the castle? The Nasrid sultan Muley Hacén, who ruled the Emirate of Granada from 1464 to 1482. Why is it sometimes called the Castle of Zoraya? After Isabel de Solís, known as Zoraya, Muley Hacén's wife, who lived with him there during his final years. Can the castle still be visited today? Remnants of the defensive walls survive on site, mainly on the northern and eastern sides, giving a sense of the fortress's original polygonal shape. What role did the castle play regionally? It controlled the route linking Granada, Alhama, the coast and the Alpujarra as part of the Lecrín Valley's defensive system.

Noria de Huerta de Ortega

Malaga

Noria de Huerta de Ortega marks the remains of an old water wheel that once irrigated one of Málaga's urban orchards nearly two centuries ago. The ground where the wheel once stood is now part of a larger social services complex run by the provincial government, yet the structure itself still bears witness to the area's agricultural past. What was the noria and what was it used for? A noria is a water wheel, traditionally powered by an animal or by the current of a water channel, long used across the Iberian Peninsula to lift water from wells or channels and direct it into irrigation systems. The surviving remains at this site date back to the second decade of the 19th century. The wheel served a nearby cultivated plot known as Huerta de Godino, a market garden that has since disappeared as the city grew around it. Why is the site named after Huerta de Ortega instead? Two historic orchards once sat side by side in this part of the city, near today's Arroyo de los Ángeles street: Huerta de Ortega and the aforementioned Huerta de Godino. The name of the first came to identify the whole plot, and in 1956 it became the site of a children's reception home, initially run by the Daughters of Charity together with provincial staff, including pediatricians, social workers, speech therapists and educators. What occupies the site today? Since 2013, the former reception centre has been reborn as La Noria, a Social Innovation Centre run by the Diputación de Málaga (the provincial council). The complex spans around 37,000 square metres in the heart of the city, right next to the Maternal and Child Hospital. The historic water wheel gave its name to the entire centre. A working vegetable garden still operates on the grounds, supplying produce to La Noria's own kitchens and to partner charities. Kitchen scraps are processed through vermicomposting, using worms to turn waste back into fertiliser for the garden, closing a small local resource loop. Is it worth a visit? This is not a conventional tourist attraction with a museum or viewpoint — it is primarily a working social centre, open to community activities, education projects and urban sustainability initiatives. For visitors interested in Málaga's agricultural history or in local social innovation work, however, it offers an interesting stop that connects the remains of an old irrigation system with a modern approach to sustainable, community-driven land use. Frequently Asked Questions What exactly is the noria at this site? It is the surviving remains of a 19th-century water wheel that irrigated the nearby Huerta de Godino orchard, which no longer exists. How old is the structure? It dates from the second decade of the 19th century, roughly two hundred years ago. Why is the site named after Huerta de Ortega if the wheel irrigated Huerta de Godino? The two orchards were neighbouring plots near today's Arroyo de los Ángeles street. The name Huerta de Ortega came to identify the wider area where the social centre was later built, which is why the whole complex is now called La Noria. What is on the site today? The La Noria Social Innovation Centre, run by the Málaga provincial council, including a vegetable garden and a food-waste vermicomposting programme. Can this site be visited like a historic monument? It functions primarily as an active social centre rather than a museum, so access depends on the activities taking place there at any given time.

House of Hylas

Santiponce

The House of Hylas is a Roman townhouse uncovered within the archaeological site of Italica, next to the modern town of Santiponce, a short distance from Seville. The building takes its name from a mosaic found inside it, one of the best-known figurative mosaics to survive from this Roman city. Where is the House of Hylas located? The house stands inside the ancient city of Italica, founded on the outskirts of present-day Santiponce. It covers roughly half of one ancient city block, and part of the structure — including where its main entrance once stood — has never been excavated or firmly identified. Why is the house named after Hylas? The name comes from a mosaic whose central figurative panel told the myth of Hylas, a young companion of Hercules during the voyage of the Argonauts. According to the legend, Hylas was sent to fetch water and was drawn into a spring by nymphs captivated by his beauty, while Hercules searched for him in vain. Specialists date this mosaic to the early second century AD. What happened to the original mosaic panel? At some point the central image of Hylas was cut out of the floor and moved to the Archaeological Museum of Seville, where it remains on display today. Only the geometric border that once framed the scene is still in place inside the house, now missing its original centerpiece. What other mosaics survive in the house? The house preserves more than one decorated floor. A dining room set at a lower level and linked to the main courtyard has a mosaic showing the four seasons. The largest dining room in the house, covering about 108 square metres, is paved with a mosaic of tigers and opens onto two internal courtyards. The two courtyards The eastern courtyard still holds traces of mosaic flooring and is bordered by decorated rooms, including a hall of around 74 square metres arranged like a dining room. The western courtyard is less well preserved; it centres on a rectangular pool, with two mosaic-floored rooms along its southern side. How was the house laid out? At the centre of the residence stood a peristyle courtyard built in the Rhodian style, meaning one of its four porticoes stood taller than the other three, with a fountain set in the middle of the open space. This arrangement, typical of high-status Hellenistic-Roman houses, separated the more formal reception rooms from private living quarters while linking them through covered walkways. Frequently Asked Questions Is the original Hylas mosaic still inside the house? No. The central panel showing Hylas being drawn into the spring was removed long ago and is now kept at the Archaeological Museum of Seville. Only the surrounding geometric mosaic remains in the house itself. How old is the house and its mosaics? The Hylas mosaic is dated to the early second century AD, a period when Italica was expanding significantly. Has the house been fully excavated? No. It occupies about half of an ancient city block, and sections of it — including the location of the entrance — have not been excavated or clearly identified. What other mosaic scenes can be seen in the house? Beyond the Hylas myth, the house contains mosaics depicting the four seasons and a scene with tigers, along with geometric decoration in both of its courtyards.

Solar Thermoelectric Energy Laboratory

Granadilla de Abona

The Solar Thermoelectric Energy Laboratory is an unfinished, abandoned research facility on the southern coast of Tenerife, in the municipality of Granadilla de Abona, close to the seaside town of El Médano. Rising above the dunes and beaches of this stretch of coastline are the skeletal remains of dish structures, each 26 metres across, once meant to track the sun and concentrate its rays through a rotating array of mirrors. Today it stands as one of the Canary Islands' most striking abandoned sites, clearly visible from nearby roads even though the structure itself is off-limits from the inside. What was the laboratory built to do? The project was designed to generate both electricity and hydrogen from concentrated sunlight. Its most experimental feature was a chemical process meant to store the captured solar heat as methanol, a method that — had it worked — would have let the site bank solar energy for far longer than conventional batteries allow. Several dish units were planned, each tracking the sun independently through mirrors mounted on a moving frame. How was construction meant to unfold? The first phase of the project, budgeted at roughly 5 million euros, was funded through a grant from Spain's Ministry of Industry awarded in 2007, with building work starting the following year, in 2008. A far larger second phase, meant to scale the concept up to full industrial output, was projected to cost around 111 million euros — a jump in scale that shows just how ambitious, and how expensive, this early solar-hydrogen experiment was meant to be. Why was the project never completed? The laboratory was built on rural land without the planning permits required for that kind of construction, and this administrative failure is what ultimately brought the project down. Work was halted three separate times before stopping for good in 2009. The construction company later sued the Canary Islands regional government, seeking 50 million euros in daily restitution counted from 9 February 2009, plus a further 40 million euros in losses. Spanish courts dismissed the claim in 2013, closing the legal dispute but leaving the structure permanently unfinished. What does the site look like now? The dishes stand unmonitored and increasingly weathered, and entering the site carries real risk since nothing has been secured or adapted for visitors. Even so, the sight of these giant mirrored dishes set against Tenerife's dry, volcanic landscape draws photographers and people with an interest in abandoned industrial sites. Wikidata lists the site simply as an "abandoned dish structure." How do you get there? The laboratory sits right on the coast near El Médano, a well-known surfing town on Tenerife's south side. Driving is the easiest option, with parking available in El Médano itself. Bus line 411 also stops within walking distance of the site. Frequently asked questions What is the Solar Thermoelectric Energy Laboratory? It's an unfinished solar-energy research facility begun in 2008, designed to produce electricity and hydrogen from concentrated sunlight. It now stands abandoned as a set of giant dish structures on the coast near Granadilla de Abona. Why was construction stopped? The site was built on rural land without the required planning permits. After three earlier halts, work stopped for good in 2009, and a legal dispute between the developer and regional authorities was resolved in 2013 when the courts dismissed the developer's claim. Can you go inside the structure? The site isn't officially open or secured, so entering it is entirely at your own risk. How do you reach the laboratory from El Médano? By car, with parking available in El Médano, or by bus line 411, which stops within walking distance of the site.

Torre del Llano

Motril

Torre del Llano is a historic coastal watchtower standing on the shoreline of the municipality of Motril, in the province of Granada, on Spain's Costa Tropical. Also known as Farillo de Calahonda, it rises on the Punta de Carchuna headland, between Carchuna and Calahonda beaches, right above the Mediterranean shore. When was the tower built? Records date its construction to 1575, crediting the mason Juan Alonso with the work. It formed part of a chain of watchtowers built along the coast of the former Kingdom of Granada to warn of raids by Barbary corsairs and pirates. Torre del Llano kept visual contact with the nearby Carchuna Castle and with the Zambullón Tower in the neighbouring municipality of Gualchos, together forming an early-warning network along the shoreline. What was the tower used for? Its garrison kept watch over the sea and guarded the anchorage at Calahonda, an important loading point on this stretch of coast at the time. Two cannons were mounted on the tower, and it was staffed by watchmen and infantry soldiers who could raise smoke or fire signals to alert nearby settlements whenever a threat appeared offshore. How did its role change in the 19th and 20th centuries? In 1863, as the port of Calahonda grew busier, the tower was fitted with a light and began operating as a lighthouse, guiding vessels toward the harbour. The light stayed in service for decades until a storm badly damaged the structure in 1936. When the Spanish Civil War broke out shortly afterward, the tower stood within a combat zone, and plans to dismantle the wrecked lighthouse fixture were halted. What remains to see today? Torre del Llano survives today as a ruin, visibly leaning and partly sunk into the ground. Despite its poor condition, it remains a recognisable landmark on this part of the coast and a stop along the seafront path connecting Carchuna and Calahonda. From around the tower, walkers get open views of the sea and the neighbouring beaches, which keeps the spot popular with people strolling the shore. How do you get to Torre del Llano? The tower sits within the municipality of Motril, on the coast between Carchuna and Calahonda, in the eastern part of the Costa Tropical. The easiest way to reach it is on foot or by bicycle along the seafront promenade linking the two villages, a route that follows the shoreline without heading inland. The surrounding area stays quiet and largely free of crowds, unlike busier stretches of the Costa Tropical. Frequently Asked Questions What other names does Torre del Llano go by? Locally it is also called Farillo de Calahonda, or simply El Farillo, a name recalling its later use as a lighthouse. When was the tower constructed? Historical sources point to 1575, with the work attributed to the mason Juan Alonso. Did the tower ever function as a lighthouse? Yes, from 1863 onward, after a light was added to guide ships into the port of Calahonda. Can visitors go inside the tower? No, the structure is a ruin in poor condition, leaning and partly sunken, so it can only be viewed from the outside.

Castell d'Empúries

l'Escala

Castell d'Empúries refers to the medieval castle ruins standing by the church square in Sant Martí d'Empúries, a small historic quarter within the municipality of l'Escala, in the Alt Empordà region of Catalonia. It is worth noting this is not the same place as the nearby, much larger municipality of Castelló d'Empúries — the ruins described here belong to a distinct, small-scale site in the old core of Empúries. Where exactly are the ruins located? The remains sit in Sant Martí d'Empúries, the historic nucleus of l'Escala, right next to the well-known Greco-Roman archaeological site of Empúries. The castle originally stood on the square beside the parish church, at the heart of the old walled settlement. Today it's a quiet corner that most visitors reach on foot after touring the ancient ruins a short walk away. What did the castle look like, and what survives today? The structure dates from the 13th and 14th centuries and was built as a rectangular, elongated building of dressed stone. What remains is one corner of that original building: a stretch of wall and an entrance portal raised roughly a metre above the level of the square. The portal is made up of three arches — two round arches built from voussoirs of different sizes, separated by the slot where a portcullis once slid up and down, and a third, flatter arch set further inside the passage. This corner is the only part of the medieval castle still clearly readable on the ground. What is the history behind these ruins? Written references go back to the late 13th century: in 1285 the castle was set on fire by the French admiral Guillem de Lodeva during the conflict between France and King Peter the Great of Aragon. A document from 1328 also names the site as "castro de Impuriis." In the 15th century, during the Catalan civil war, the castle suffered serious damage. After 1479, King John II of Aragon granted the property to Pere de Torroella, who rebuilt its walls. By the 17th century the castle belonged to the Margarit family before being sacked by the troops of King Philip IV, most likely during the Reapers' War. From that point the building was left to decay, gradually reaching the ruined state visible today. Why is this small site worth a stop? The remains are listed in Catalonia's Inventory of Architectural Heritage as a protected historic monument. It's a modest site in physical terms, but one tied to centuries of border disputes and civil conflict across the Empordà region. A lesser-known detail: the castle is said to have inspired the home of the hero in "Capitán Trueno," one of the most popular characters in postwar Spanish comic-book culture. Frequently Asked Questions Is Castell d'Empúries the same as Castelló d'Empúries? No. Castelló d'Empúries is a separate, larger municipality in Alt Empordà, while these castle ruins stand in Sant Martí d'Empúries, within the municipality of l'Escala. How long does it take to see the ruins? Only a few minutes are needed for the portal and wall themselves, though most visitors combine it with a short walk through Sant Martí d'Empúries. Can this be combined with a visit to the Empúries archaeological site? Yes — the Greco-Roman ruins of Empúries sit right next door, and pairing the two is the most common way to explore the area. From which period does the castle date? From the 13th–14th centuries, though it was damaged and rebuilt several times up to the 17th century.

Castillo

Moguer

Castillo de Moguer stands at the heart of the small town of Moguer, in the province of Huelva, Andalusia, in southwestern Spain. Only fragments of the original fortress survive today — three of its four towers and stretches of its walls — yet for centuries this stronghold served as the town's military, administrative, and judicial center. How old is the castle, really? The site's story begins long before any castle stood here. A Roman watchtower once occupied the spot, with the buildings of a rural estate clustered around it. Following the Muslim conquest, the settlement grew into an alquería, a rural hamlet typical of al-Andalus. The fortress itself, in the form recognizable today, was raised in the 12th century, during a period when the Almohads were pushing forward a broad program of military construction around Seville and Niebla. The earliest surviving written records mentioning the castle, however, date only from the mid-14th century — the same period when the structure was substantially enlarged and reworked. What did the castle look like, and what was it used for? The floor plan is an irregular square, roughly 44 by 45 metres across, with a tower rising at each of the four corners. The town of Moguer itself grew up around this fortress, using it as an anchor point for its earliest streets and houses. Over the centuries the castle carried three roles at once: a military stronghold, an occasional residence for the local feudal lord, and a jail. It kept performing these functions right up until the second half of the 18th century, when it was finally abandoned. What remains to see today? Recognition came long after abandonment: in 1949 the castle was declared a Monumento Nacional, Spain's National Monument designation. Three of the original four corner towers still stand, along with sections of the perimeter wall. Part of the site has been brought back into use — the old weapons yard, the patio de armas, now houses the town's tourist information office, giving visitors a reason to step inside the walls and see the surviving stonework up close. Why stop here while in Moguer? Moguer is a compact town, and the castle sits at its historical center, just a short walk from the main square. It offers a quick, tangible sense of how the town's earliest defensive core was laid out before it grew beyond its walls. The layers visible in the stone — a Roman watchtower, an Almohad fortress, a 14th-century expansion — mean that several centuries of history sit stacked on top of one another in the same spot. Frequently Asked Questions Where is Castillo de Moguer located? In the centre of the town of Moguer, in the province of Huelva, Andalusia, in southwestern Spain. How old is the castle? The fortress in its developed form dates to the 12th–14th centuries, though the site was already occupied and fortified in Roman times. Can visitors go inside today? Yes. Only part of the original structure survives — three towers and sections of wall — but the former weapons yard now houses the town's tourist office, which is open to visitors. What was the castle used for historically? It served three purposes at once: a military post, an occasional residence for the local feudal lord, and a jail, a role it held until it was abandoned in the second half of the 18th century. Is the castle a protected monument? Yes, it was officially declared a Monumento Nacional (National Monument) in 1949.

Batería J4

Baiona

Batería J4 is a coastal artillery battery hidden in the woods of Montes de Baredo, a few kilometres from the centre of Baiona in the province of Pontevedra, guarding the southern side of the mouth of the Ría de Vigo. Abandoned and now partly in ruins, the site spent decades watching over the Galician coast and remains one of the most striking military relics in the area. Where exactly is Batería J4? The battery sits on the hills above Cabo Silleiro, right next to the Silleiro lighthouse (Faro de Silleiro), with views over the mouth of the Ría de Vigo and Baiona Bay. Together with the neighbouring J5 battery, it forms a single military complex in the parish of Baredo. Both batteries belonged to a defensive network protecting the Rías Baixas, which also included the batteries at Monteferro (J3), Cabo Udra (J2), A Guía (J6) and O Grove (J1), positioned so their fields of fire overlapped and covered each other. When was it built, and why? The first two guns arrived in 1923, salvaged from a decommissioned Spanish warship. A third gun was added in the early 1940s, and the battery reached its final layout in 1943, part of a wider postwar effort to replace the region's outdated coastal defences after the Spanish Civil War. Spanish and German engineers both worked on the underground galleries and shelters. The battery's job was to control access to the Ría de Vigo and Baiona Bay, guarding against a naval attack that never came. What weapons did the battery carry? At full strength the battery held four Vickers guns of 152.4 mm calibre, with a maximum range of 21,600 metres. The guns could be fired manually or switched to an automatic electric mode that let all four positions open fire together. Operating a single gun took around nine soldiers, and the battery's full garrison numbered more than fifty. A coastal artillery regiment ran the site for over five decades. What survives on site today? The complex includes roughly 200 metres of underground tunnels fitted with rail tracks for moving ammunition, four gun emplacements, a fire-control and observation bunker, barracks, a canteen, stables, a water cistern and other support buildings. At its thickest point, the rock cover protecting the galleries reaches 14 metres. One of the 15.2 cm guns still stands on site, its barrel capped, and it is the most recognisable landmark among the ruins. Can visitors reach Batería J4? The battery kept a small garrison until the early 1990s and was finally abandoned in 1998. Since then the buildings have decayed and suffered vandalism, and the interiors are closed off. The ruins themselves, however, can be reached on foot along a coastal path near the Silleiro lighthouse, a route popular with hikers and history enthusiasts, as shown by the many visitor photos and reviews of the site. Frequently Asked Questions Where is Batería J4 located? On the hills of Cabo Silleiro, in the parish of Baredo, a few kilometres from Baiona, at the mouth of the Ría de Vigo. When was the battery built? The first guns were installed in 1923, and the full battery was completed in 1943. What weapons did it have? Four Vickers guns of 152.4 mm calibre with a range of up to 21,600 metres. Can you go inside the bunkers? No, the interiors are sealed, but the ruins are visible from the outside along the coastal footpath. Until when was the battery operational? It was abandoned in 1998, though it kept only a small garrison from the early 1990s onward.

La Barranca sanatorium

Navacerrada

La Barranca Sanatorium once stood in the mountains above Navacerrada, roughly 50 km northwest of Madrid, and for most of the twentieth century served as a hospital for tuberculosis patients. Although the building no longer exists, its history offers a striking window into how Spain fought respiratory disease long before antibiotics were available. What was this building originally built for? Construction finished in 1941, commissioned by Spain's National Anti-Tuberculosis Board (Patronato Nacional Antituberculoso). Tuberculosis was one of the country's leading causes of death at the time, and reliable drug treatments were still decades away — penicillin and streptomycin only became widely available later. Doctors instead relied on what was known as climate therapy: isolating patients in clean mountain air and sunlight, away from towns, in the hope that this would help the body fight the infection. The Sierra de Guadarrama, dry and set above 1,200 meters, was considered an ideal spot for this kind of institution, and its remote location also kept the healthy population away from contagion. What did the complex look like? The sanatorium occupied a plot of roughly 3,000 square meters and consisted of two main wings joined by a central section, along with additional annexes and basement levels — eight floors in total, five of them main stories, rising to about 36 meters. Large windows ran along the facades, designed to flood the wards with natural light and fresh air, in line with the medical thinking of the era. How did its role change over time? Once antibiotics made tuberculosis treatable, the country's network of dedicated sanatoriums lost its original purpose almost overnight. The Navacerrada building was converted into a psychiatric hospital, but this second life was short — it functioned in that capacity for only about five years, roughly between 1990 and 1995, before closing due to budget shortfalls and a series of incidents that damaged its reputation. Why does the site have such a dark reputation? After closing, the building sat empty for close to twenty years, slowly falling apart — interior partitions collapsed or were stripped away, leaving mostly bare structural pillars standing. That decay, combined with the building's brief history as a psychiatric facility, fed a reputation for being haunted: locals and urban explorers alike reported strange noises and voices inside, and the ruins became a popular, if illegal, destination for abandoned-place explorers. Can visitors still see it today? No — the structure is gone. Because of its unsafe condition and its location inside the Sierra de Guadarrama National Park, authorities ordered its demolition, a project costing around 3.5 million euros. Crews used mechanical methods rather than explosives, and the work — aimed at restoring the site to its natural state — took about nine months, starting around the turn of 2023 into 2024. Anyone visiting Navacerrada today will find mountain scenery and hiking trails through the national park, but not the sanatorium building itself — worth knowing before planning a trip built around its history. Frequently Asked Questions Where was La Barranca Sanatorium located? In the mountains above Navacerrada, within the Sierra de Guadarrama, about 50 km from Madrid, at an elevation above 1,200 meters. When was it built? In 1941, as a tuberculosis hospital run by Spain's national anti-tuberculosis authority. Is the building still standing? No. Due to its poor condition and location inside a national park, it was demolished between 2023 and 2024. Why was it considered haunted? Decades of abandonment following a brief and troubled run as a psychiatric hospital (1990–1995) gave rise to local ghost stories and reports of strange sounds among the ruins.

Oreja

Ontígola

Oreja is a deserted village and ruined medieval castle in the municipality of Ontígola, in the eastern part of Toledo province, Castilla-La Mancha, Spain. Perched on the limestone plateau known as the Mesa de Ocaña, the site today draws mainly history enthusiasts and hikers looking for an off-the-beaten-path destination in the region. Where does the name Oreja come from? The name traces back to Aurelia, a Roman settlement that once occupied the site. Over the centuries the Latin name gradually shifted in Spanish until it became "Oreja." The medieval fortress was built directly over the older Roman position, taking advantage of its naturally defensible hilltop location. How did the castle change hands over the centuries? For much of the Middle Ages, the stronghold at Oreja was contested ground between Muslim rulers and the Christian kingdoms of the Iberian Peninsula. King Alfonso VI of León and Castile gained control of it as part of the dowry from his wife Zaida, but after the Christian defeat at the Battle of Uclés in 1108, the castle fell back into Muslim hands. In 1113 the commander Mazdalí seized it and turned it into a base for raids against Castilian forces; a serious defeat of Christian troops in the area followed in 1132. The tide turned under Alfonso VII, who besieged the castle for roughly six months with combined forces from Toledo, Extremadura, Galicia and León. The garrison surrendered in 1139, worn down by hunger and thirst, and the settlement was repopulated with Christian settlers. Later, Alfonso VIII granted Oreja to the Order of Santiago, which used the fortress as a defensive outpost against Almohad incursions. What happened to the castle afterward? By the 15th century the estate had passed to Gutierre de Cárdenas, and later to the counts of Colmenar de Oreja and the dukes of Frías. Once the fortress lost its military value and living conditions on the exposed hilltop grew increasingly difficult, residents began moving gradually to the nearby towns of Ontígola and Aranjuez. The village was definitively abandoned in the 1960s. What is there to see today? Oreja today consists of extensive, heavily deteriorated ruins — the remains of the castle walls alongside the abandoned village houses — and the site appears on Spain's Red List of endangered heritage due to its ongoing decay. Its main appeal lies in its landscape and historical value: sweeping views over the surrounding valley and tangible traces of centuries spent on the shifting Christian-Muslim frontier. Every year on August 15, descendants of the former inhabitants gather at the site to celebrate the old village's patronal festival, briefly bringing the abandoned settlement back to life. How can visitors get to Oreja? The ruins lie within the municipal boundaries of Ontígola, within easy reach of both Aranjuez and Toledo. Given the site's ruined state and lack of tourist infrastructure, it is best treated as a walking destination — bring water and sturdy footwear, since the terrain is uneven and shade is scarce. Frequently Asked Questions What is Oreja? It is the ruined medieval castle and deserted village in the municipality of Ontígola, Toledo province. Where does the name come from? From the Roman settlement of Aurelia, whose name gradually evolved into "Oreja." When was the village finally abandoned? Its final abandonment took place in the 1960s. Can visitors reach the site independently? Yes, it lies within the Ontígola municipality and can be reached on foot, though there is no developed tourist infrastructure.

castell d'Espasens

Fontcoberta

Castell d'Espasens is a medieval stronghold in the hamlet of Espasens, part of the municipality of Fontcoberta, in the Pla de l'Estany comarca, Girona province. It sits on a low rise at roughly 181 metres above sea level, right next to the church of Santa Caterina d'Espasens, forming one of the more interesting heritage stops in this quiet part of Catalonia. Where exactly is the castle located? Espasens is a small hamlet within Fontcoberta, a few kilometres from the town centre. The surroundings are rural through and through — farmland, gentle hills, and scattered farmhouses. The castle occupies one of these low hills, a position that once let its occupants keep watch over the surrounding road and fields. Where did the castle and the Espasens family come from? Some form of settlement on this spot is thought to date back to the 10th century, though what visitors see today are the remains of a fortified house, known locally as a casa forta, built in the 14th or 15th century, most likely on the footprint of an earlier residence. The site takes its name from the Espasens family, documented in medieval records over several centuries. Berenguer d'Espasens is recorded as lord of the place in 1332, and Ramon d'Espasens held the castle in 1363, along with rights to a third of the tithes from the parish of Ollers. What happened to it in later centuries? A later Berenguer d'Espasens controlled the property between 1432 and 1444 and was the last family member to carry that surname. Ownership passed to Guillem Arnau de Palol in 1480, and his family kept the estate for generations afterward. Interestingly, a man named Ramon d'Espasens was still recorded living in Espasens as late as 1903, a sign of how long the old family name lingered in local memory, long after the family itself had lost the property. What is left to see today? What survives is modest but legible. The site has been cleared of earth and rubble, revealing the outline of a rectangular room on the eastern side, originally covered by two arched vaults. The perimeter walls still stand at around a metre in height, with a thickness of 70 to 100 centimetres. A ditch, likely a former moat, is also visible around part of the site. The overall scale suggests this was never a large fortress, but rather a fortified family residence. The remains are listed in Catalonia's architectural heritage inventory under reference MPE-3010, though they carry no formal protection status of their own today. The site is easy to reach and open to visitors, and its closeness to the church of Santa Caterina makes it easy to combine both stops in a single walk through the area. Frequently Asked Questions Can you visit Castell d'Espasens? Yes. The ruins are freely accessible, with no booking or entrance fee required. How old is the castle? Traces of occupation on the site go back to the 10th century, but the walls still visible today belong to a fortified house built in the 14th or 15th century. Is it worth combining with other sights in Fontcoberta? Yes — the church of Santa Caterina d'Espasens stands just steps from the ruins, and the wider municipality of Fontcoberta offers several viewpoints over the rural Pla de l'Estany landscape. Can you still make out the original layout of the castle? Only partly. The outline of one room, sections of the perimeter wall, and the ditch are all visible, but given the small size and state of the remains, reconstructing the full original layout isn't really possible.

Torre de Brió

Sant Miquel de Campmajor

Torre de Brió (also known as Torre de Briolf) is a ruined medieval tower standing in Sant Miquel de Campmajor, a small municipality in the Pla de l'Estany comarca, Girona province, Catalonia. The tower rises in Briolf, a long-abandoned hamlet, right next to the Romanesque church of Sant Esteve de Briolf, and counts among the most distinctive historic remains in this rural corner of Catalonia. Where exactly is the tower located? The tower stands just west of the church of Sant Esteve de Briolf, at roughly 268 meters above sea level, close to coordinates 42°10' N, 2°41' E. Briolf itself has been uninhabited for a long time — today it's more a place-name on a map than an active settlement, surrounded by the rolling fields and woodland typical of inland Pla de l'Estany. What does the tower look like? Built on a square floor plan, the tower is made of squared ashlar stone blocks, each typically 20–25 cm high and 30–50 cm long. Its walls are notably thick, reaching up to a meter in places, while the interior measures about 4.1 meters across. Only the ground floor and first floor survive; any upper levels have long since collapsed or been dismantled. The ground-floor entrance is topped by a semicircular arch, while the arch above it, leading to the first floor, is badly damaged. The building originally had two doors — one facing east on the ground floor, another facing south on the first floor — both framed by triangular lintels. A distinctive group of three windows opens on the west and north walls of the first floor. Who built it, and when? The place-name Briolf already appears in written records from the 10th century, when the settlement — recorded as Briulfo — was mentioned in the will of Count-Bishop Miró and left to the monastery of Sant Pere de Besalú. The tower itself is younger: it was raised in the 12th century, a period when this type of fortified farmhouse, known in Catalan as a "mas de torre," was typically built by lesser knightly nobility or well-off peasant landholders. Such towers combined a defensive role with everyday use, and some served as the residence of a local bailiff acting on behalf of a feudal lord. What condition is the tower in today? Torre de Brió is now a ruin. It has lost its roof and upper sections, and the remaining walls show clear signs of deterioration. It is physically possible to step inside, but doing so is discouraged because parts of the structure are unstable and could collapse. The tower is protected as a Bé Cultural d'Interès Nacional (BCIN), Catalonia's highest level of heritage protection, and is listed in the regional heritage catalog under the reference ARCAT MPE-3126. The municipality of Sant Miquel de Campmajor has commissioned a conservation master plan covering both the tower and the neighboring church of Briolf. How do you get there? Reaching the site takes some effort. The final stretch of road is in poor condition, so a four-wheel-drive vehicle is recommended for that last part of the journey. From the nearest parking spot, visitors should expect roughly a 45-minute walk on foot, through the hilly, partly wooded terrain typical of the Pla de l'Estany countryside, well off the region's main tourist routes. Frequently asked questions What is Torre de Brió? It is a 12th-century "mas de torre," a fortified tower-house, standing in the abandoned hamlet of Briolf within the municipality of Sant Miquel de Campmajor. Can visitors go inside the tower? Physical access to the interior is possible, but not recommended, since parts of the structure are damaged and at risk of further collapse. Is the tower a protected heritage site? Yes. It holds BCIN status (Bé Cultural d'Interès Nacional), Catalonia's top heritage protection category, catalogued under reference ARCAT MPE-3126. How do you get to Torre de Brió? The last section of the access road requires a four-wheel-drive vehicle, and reaching the tower from the nearest parking area takes about a 45-minute walk.

Mas Montjoi de Baix

Roses

Mas Montjoi de Baix is a Catalan masia — a traditional country estate — standing east of the town centre of Roses, in the Montjoi valley, within the Alt Empordà comarca of Catalonia. From the outside it looks like an ordinary rural farmhouse, yet beneath its floors archaeologists have uncovered traces going back to the Visigothic era, making it one of the more unexpected archaeological sites near Roses. What does the building look like? The estate consists of a rectangular structure made up of three adjoining sections, arranged around a square defensive tower — a layout typical of fortified Catalan masies built to withstand raids in earlier centuries. The property is listed as a cultural asset of local interest. What did the excavation uncover? About six years before 2026, archaeological work began at the site alongside renovation of the farmhouse. The dig, led by archaeologist Marcel Pujol, brought to light the remains of two churches dated to between the 7th and 9th centuries, together with a large water tank divided into three compartments. Burials found around the churches included one grave from the 7th century and two infant burials from the 9th century. Because so little pottery survived on site, the graves were dated using radiocarbon (carbon-14) testing on the human remains themselves. Which religious complex once stood here? Historical records had long referred to a monastic complex known as Magrigul at this location, made up of three churches dedicated to Saint Michael the Archangel, the Saviour, and the Virgin Mary. Until the excavation, that complex was known only from documentary sources — the finds at Mas Montjoi de Baix provided the first physical evidence that it really existed. One of the churches shows signs of having been destroyed during the Muslim invasion and was never rebuilt afterwards. How is Montjoi connected to the nearby Trencada estate? Records show that the extensive landholdings of the main house at Trencada, also known as Mas d'En Coll, once extended to include the Montjoi estate. That shared ownership explains why identical pieces of farm equipment — used for pressing olives and grapes — turn up at both properties. Can visitors already explore the site? For now, the property is not open as a signposted visitor route. Researchers are waiting on a conservation and museum-display plan before the site can be presented to the wider public. Until then, Mas Montjoi de Baix remains primarily an active research site rather than a stop on Roses' tourist map. Frequently Asked Questions Where exactly is Mas Montjoi de Baix located? The estate sits east of the town centre of Roses, in the Montjoi valley, within the Alt Empordà comarca of Catalonia. What was found during the archaeological dig? The remains of two Visigothic-era churches (7th-9th centuries), a three-part water tank, and several burials, including two infant graves. Does the site connect to a former monastery? Yes — the excavation confirmed the existence of the Magrigul religious complex mentioned in historical documents, made up of three churches. Is the site open to the public? Not yet as an organised visit — a conservation and museum-display plan is still being prepared.

Torre del Barranc d'Aigües

el Campello

Torre del Barranc d'Aigües is a 16th-century watchtower in El Campello, in the province of Alicante on the Costa Blanca. Spanish-language sources also refer to it as Torre de Aguas, Torre de Reixes, or Torre de Lloma de Reixes — all names for the same structure, reflecting local naming conventions rather than different buildings. The tower sits on a rise above the small cove of Cala del Barranc d'Aigües, within a protected area valued for its landscape, and although it has suffered from decay over the years, enough of its original shape remains visible to make out its layout. Why was this tower built? Torre del Barranc d'Aigües belonged to a chain of watchtowers raised along the Valencian coastline during the 16th century. Their purpose was to spot Barbary corsair ships approaching from the sea and warn nearby communities of danger, relaying signals by fire or smoke from one lookout point to the next along the shore. Structures like this one were built for function rather than display, and they remain among the clearest physical traces of the coastal defense system that once protected this stretch of the Mediterranean. What older history does this stretch of coast carry? The area around the tower has a history that predates the watchtower itself by centuries. Until 1296, this territory marked the border between the Kingdom of Castile and the Kingdom of Aragon. That changed when King James II annexed the land to the Crown of Aragon. As a result, the site layers two distinct historical periods: a medieval border dispute and, much later, an early modern coastal defense network built against piracy. What condition is the tower in today? Torre del Barranc d'Aigües holds the status of Bien de Interés Cultural, Spain's designation for sites of cultural significance, which is meant to guarantee a degree of protection. In practice, the structure has continued to deteriorate over the years, with the upper section suffering the most damage. Even so, the remaining part of the tower has kept enough of its form to allow visitors to trace its original outline. In recent years, initiatives have emerged aimed at halting further decay and carrying out conservation work, though progress has been gradual. How do you get there, and what else is worth seeing along the way? A simple hiking route of just over 2.5 kilometers round trip leads to the tower, with a gentle incline that makes it accessible to most visitors regardless of fitness level. The path crosses an area prized for its scenery, passing near a scenic viewpoint marked by a trig point. From the top, next to the tower, the views stretch across the coastline and surrounding hills, which is the main reason the route draws regular visitors in El Campello. Frequently Asked Questions Are Torre del Barranc d'Aigües and Torre de Reixes the same tower? Yes. It is the same structure, known under several names — the Valencian Torre del Barranc d'Aigües, the Castilian Torre de Aguas, and a name derived from the nearby rise of Lloma de Reixes. When was the tower built? It dates to the 16th century and formed part of a network of coastal watchtowers built along the Valencian shore to warn against Barbary corsair raids. Is the tower legally protected? Yes, it holds the status of Bien de Interés Cultural, although in practice its condition has continued to decline over the years, particularly in the upper part of the structure. How long is the hike to the tower, and is it difficult? The round trip covers just over 2.5 kilometers with a gentle slope, making it accessible to most visitors, including families with children.

Torre de Mariola

Bocairent

Torre de Mariola Torre de Mariola is a medieval watchtower standing on the Alto de Mariola hill, within the municipality of Bocairent, in the province of Valencia, Spain. It rises inside the Sierra de Mariola mountain range, close to a well-known local rest spot around the Casa and Fuente de Mariola. Only part of its walls survive today, but the tower still commands attention through its setting — from the hilltop, the view stretches over the valleys separating the coast from the interior of the region. Where does the tower come from? The structure visible today dates back to the Islamic period, most likely the 11th century. The tower served as a lookout and control point, positioned to watch over routes used to travel between the coastline and inland areas. The hill itself was occupied much earlier — traces of human presence go back to the Bronze Age — but the surviving walls belong specifically to the Muslim-era construction. What does it look like now? The tower stands in a partially ruined, "beheaded" state, missing its upper section. What remains reaches around five metres in height, with some walls as thick as 1.5 metres, a detail that gives a sense of how solidly these defensive points were built. Despite the centuries, the shape of the structure is still legible, offering a clear picture of how the watch system across this part of Valencia once worked. Because of its historical value, the tower is protected as a Bien de Interés Cultural (BIC), Spain's highest level of heritage protection. How do you get there? Torre de Mariola sits in mountainous terrain, so reaching it involves a short hike from the recreational area around the Casa and Fuente de Mariola. It is a popular stop for people exploring the Sierra de Mariola on foot or by bike — trails through the range connect several nearby towns, and the tower itself is a natural destination thanks to the views it offers over the surrounding landscape. What else is worth seeing nearby? The area around the tower has strong natural and cultural appeal. The Sierra de Mariola is a protected natural area, known for its biodiversity and for a long-standing local tradition of gathering wild herbs. Bocairent, the municipality the tower belongs to, is a town with a well-preserved medieval layout, making it a worthwhile stop when combined with a trip into the mountains. Frequently Asked Questions What period does Torre de Mariola date from? The surviving walls date to the Islamic period, most likely the 11th century, although the hill itself was inhabited as early as the Bronze Age. Can you go inside the tower? The structure is partially ruined and missing its upper section, so visits are limited to viewing the surviving walls from the outside and the immediate surroundings. What was the tower used for? It functioned as a watch and control post, overseeing movement between the coast and the interior from its dominant position on the hill. Is Torre de Mariola a protected site? Yes, it holds Bien de Interés Cultural (BIC) status, Spain's highest category of heritage protection. How do you reach the tower? The easiest approach is on foot from the recreational area at Casa and Fuente de Mariola, a popular starting point for trails through the Sierra de Mariola.

Torre de Mal Paso

Castellnovo

Torre de Mal Paso is a stone watchtower standing on a hill near Castellnovo, in the Alto Palancia region of Castellón province, Spain. Listed as a cultural heritage site, it is one of the more intriguing yet lesser-known landmarks of this part of the Valencian Community. Where is the tower located? The structure sits roughly a mile and a half northwest of Castellnovo, along the old road that once connected the village with neighboring Segorbe. It is visible from the village center, making it a handy landmark for anyone exploring the area on foot. A well-kept trail starts near the historic road and leads up to the site — an easy walk that does not require special preparation. What can you actually see there? Only the base of the tower survives today; the upper sections were lost to time and weathering. What remains shows a circular floor plan, built from roughly hewn masonry with no decorative elements. One curious detail is the ground-level doorway, facing south — an unusual choice for a defensive structure, since such towers typically had raised entrances that were harder for attackers to reach. Around the tower lie traces of a much older Iberian-Roman settlement: the outlines of former walls, scattered pottery fragments on the surface, and two earthen mounds that researchers believe may be the remains of larger, square-shaped towers, first documented during excavations carried out in 1946. Based on the building materials used, Torre de Mal Paso itself is thought to date from the late Roman or early medieval period, and some of its stone may have been reused from the earlier settlement nearby. What is the history behind the site? The hill and its surroundings have been inhabited for a very long time. In a nearby cave known as the Cueva de la Torre del Mal Paso, archaeologists have found burials dating back to the Neolithic period, along with stratified graves from the Iberian era. Evidence of continued use of the area spans several periods, from Romanized Iberian communities through to the late Western Roman Empire. The cave's excavated materials were revisited by researchers decades after the original findings were published, with later studies focusing on how the site was used during the Iberian Iron Age, mainly between the 3rd and 1st centuries BC. The tower itself functioned as a lookout post with defensive features — a classic example of a watchtower positioned to oversee movement along the route between Castellnovo and Segorbe, as well as the surrounding valley. Why is it worth a visit? Torre de Mal Paso appeals to travelers who enjoy pairing a short hike with a glimpse into layered history — from prehistoric burials through the Iberian and Roman periods to the medieval era. The site appears on local tourist routes in the Castellón region, including cycling itineraries that pass through Castellnovo, so it can easily be combined with other stops on a longer day out in Alto Palancia. Frequently Asked Questions How do you get to Torre de Mal Paso? Castellnovo is the best starting point. From there, a marked trail begins near the old road to Segorbe and leads to the hill, about a mile and a half from the village center. What has actually survived of the tower? Only the lower part remains — a circular stone base without ornamentation. The upper structure did not survive to the present day. How old is the tower? Based on its construction materials, researchers place it in the late Roman or early medieval period, though the exact building date is unknown. Are there other archaeological remains nearby? Yes. Traces of an Iberian-Roman settlement surround the tower, and the nearby Cueva de la Torre del Mal Paso has yielded Neolithic burials as well as materials from the Iberian Iron Age.

Fort of El Sarchal

Ceuta

Fort of El Sarchal (Fuerte del Sarchal) is an 18th-century coastal artillery fort in Ceuta, the Spanish exclave on the northern coast of Africa. It stands at the eastern edge of the city, right along the shoreline at the foot of Mount Hacho, and is the only fort of its kind in Ceuta — even though similar coastal defenses were common elsewhere in Spain. Where is the fort located? The Fuerte del Sarchal sits on the city's southern coastal defense line, in the shadow of Mount Hacho, a landmark that has guided sailors and defenders of Ceuta for centuries. Its coordinates are roughly 35.890141 N, 5.296832 W. Ceuta's compact size makes getting around easy — the whole city can be crossed by car in a matter of minutes, and the fort borders the neighborhood that shares its name, Sarchal. What does the fort look like, and what was it built for? The structure is a bastioned fort: a rectangular building with a semicircular artillery battery at its center, designed to fire on targets at sea. It was built in 1714 as part of a broader coastal fortification system that Ceuta expanded after a long siege by Sultan Moulay Ismail, which dragged on intermittently from 1694 to 1727. The same defensive program produced other strongholds nearby, including the Santa Catalina fort and the Desnarigado fort — together forming a line of coastal artillery shielding Ceuta from the sea. Over the following decades, the fort's role shifted along with the garrison's needs. It served at various times as a gunpowder store and as a military laundry. In the 1920s the building was converted into a prison, and it was this chapter that would go on to shape the fort's lasting identity in local memory. Why is the fort tied to a history of repression? After the Francoist uprising broke out in 1936, the Fuerte del Sarchal took on the role that gave it the name by which it is best known today — a prison holding women aligned with the Republican side. This period is at the center of the site's local historical memory, and it comes up increasingly often in discussions about commemorating victims of Francoist repression in Ceuta. What condition is the fort in today? Even though the building was declared a Bien de Interés Cultural in 1995 — Spain's designation for a legally protected cultural heritage site — the Fuerte del Sarchal has stood abandoned for years. It has fallen into disrepair, serves as an unofficial dumping ground, draws graffiti, and occasionally shelters homeless people. Local authorities and civic groups have been discussing giving the site formal recognition as a memorial place, a step that could open the door to its restoration. Is it worth planning a visit? The fort currently has no organized visitor access — there is no tourist infrastructure, and the building's condition makes exploring the interior inadvisable. Still, anyone interested in military history and coastal fortifications can view the structure from outside while walking Ceuta's eastern shoreline near Mount Hacho. It makes for an easy stop alongside the city's other former coastal defenses. Frequently asked questions When was the Fuerte del Sarchal built? It was built in 1714, part of a coastal fortification system erected after the siege of Ceuta by the forces of Sultan Moulay Ismail (1694–1727). What was the fort originally used for? It was a coastal artillery fort meant to defend the city from the sea; later it also served as a gunpowder magazine and a military laundry. Why is the fort known for its prison history? It was converted into a prison in the 1920s, and after 1936, during the Spanish Civil War, it held women linked to the Republican movement. Can visitors go inside the fort today? There is no organized tourist access — the building is abandoned and neglected despite being declared a Bien de Interés Cultural in 1995. It can only be viewed from the outside.

Vila-rasa

Sant Jaume de Frontanyà

Vila-rasa is an abandoned masia — a traditional Catalan farmhouse — standing in the municipality of Sant Jaume de Frontanyà, in the Berguedà comarca of northern Catalonia. The building sits at roughly 1,045 metres above sea level, east of the village centre, at the foot of the stream that shares its name. Where exactly is Vila-rasa? The farmhouse lies outside the built-up area of the village, surrounded by the steep terrain typical of Berguedà. The most straightforward approach follows the Les Planes path, passing Cal Cintet and the site of the former lignite mines known locally as the Mines de Vila-rasa. An alternative route runs via Cal Cintet and Canemars. What does the building look like? Vila-rasa is an example of 16th-century vernacular rural architecture. The floor plan is thought to be rectangular, with a ground floor and two upper storeys; the main façade faces south, with the roof ridge running parallel to it. The walls were built from rough rubble stone bonded with lime mortar, with dressed stone reinforcing the corners. The double-pitched roof is covered with Arabic-style tiles set on a timber frame. A simpler annex was added on the western side — a single-storey structure built partly with cement mortar, suggesting a later construction phase. What is the history behind Vila-rasa? The earliest record of Vila-rasa appears in the 1553 fogatge, a tax census, which names Francesch Vilarasa as its owner. Sixteenth-century documents show the farmhouse contributing to the funding of local church works; Vila-rasa was regarded as a notable fortified house (casa forta) within the municipality, though it did not rank among the most prominent estates, a group that included Vinyes, Picanyes, Cortines, Lloberes d'en Cosp and Frontanyà. Records also link the Molí del Quirze mill to the Vilarasa family. The house remained inhabited until the mid-20th century, after which it began to fall into ruin. What condition is Vila-rasa in today? The masia is now in poor, ruinous condition, overgrown with vegetation that makes it difficult to trace the original layout of its rooms. The building stands abandoned, serves no current use, and carries no heritage-protection status. The land is privately owned, and reaching the site can be difficult due to overgrown paths and steep surroundings. Is Vila-rasa worth visiting? Vila-rasa appeals more to hikers and enthusiasts of rural architecture than to typical sightseers — there is no visitor infrastructure and no marked trail leading solely to the ruin. Still, the walk there crosses attractive Berguedà countryside, passing former lignite mines and historic farmhouses such as Cal Cintet along the way. Frequently Asked Questions What is Vila-rasa? It is an abandoned 16th-century masia (farmhouse) in the municipality of Sant Jaume de Frontanyà, in the Berguedà comarca. Can the building be visited inside? No — Vila-rasa is in ruins, sits on private land, and holds no protected-heritage status, so it is not set up for visits. How do you get to Vila-rasa? The easiest way is along the Les Planes path from Sant Jaume de Frontanyà, passing Cal Cintet and the former lignite mines; an alternative route goes via Cal Cintet and Canemars. How do we know the farmhouse existed in the 16th century? The oldest surviving record is the 1553 fogatge (tax census), which lists Francesch Vilarasa as the owner.

Castle of Mesía

A Pobra

Mesía Castle (Spanish: Castillo de Mesía, also known as the Torre-fortaleza de Mesía) stands above the village of A Pobra, in the municipality of Mesía, in the province of A Coruña, Galicia. How old is the castle at Mesía? The stronghold dates from the turn of the 13th and 14th centuries. It sits on a rocky rise above the Samo river, a spot chosen for more than the view: an old route linking the A Mariña region with Santiago de Compostela — including the road between Betanzos and Santiago — passed nearby, so whoever held the crossing held real leverage over trade and travel through this part of Galicia. What did the fortress originally look like? Its layout was roughly circular, an unusual choice for Galician military architecture, where rectangular or irregular plans were the norm. Several flanking towers reinforced the perimeter, and a keep stood inside the walls as the last line of defence. A deep moat ran around the whole complex, and in places the walls climbed to eighteen metres. What part did the castle play in local history? From the 15th century onward, under the Ancien Régime, the castle served as the seat from which the jurisdiction of Mesía was administered on behalf of the archbishop of Santiago de Compostela — making it a centre of church authority over the surrounding population, not just a defensive post. In 1467, during the Irmandiño uprisings, when Galician peasants and lesser nobles rose up against the region's lords and clergy, the fortress was partly destroyed. It was later rebuilt by Alonso II de Fonseca, who restored its role as a stronghold of regional power. What condition is the castle in today? The building still stood largely intact as late as the 19th century, but gradual abandonment and a lack of upkeep since then have left it in ruins — what remains today are sections of the perimeter walls and towers. Even so, on 17 November 1994 Spain's Ministry of Culture declared it a Bien de Interés Cultural, the country's designation for heritage sites of special significance. The ruins now function as an informal emblem of the municipality of Mesía and appear on its coat of arms. How do you get there, and what should you know before visiting? The castle sits right next to A Pobra, a village that falls administratively under the municipality of Mesía, inland from Galicia's coast. The surrounding countryside is rural and hilly, shaped by the Samo river valley, with small settlements and farmland rather than tourist infrastructure. Since the site is an unstaffed ruin with no ticket office or signage, it's worth timing a visit for dry weather, when the uneven ground underfoot is easier to manage, and going in expecting to explore the ruins on your own rather than follow a guided route. Frequently asked questions How old is Mesía Castle? It was built around the turn of the 13th and 14th centuries, making it over seven hundred years old. Why was the castle built in this particular spot? It stands on a rocky rise above the Samo river, beside a route connecting the A Mariña region with Santiago de Compostela — a crossing worth controlling for its strategic value. What happened to the castle during the Irmandiño uprisings? In 1467 it was partly destroyed by rebelling peasants and lesser nobles, then later rebuilt by Alonso II de Fonseca. Does the castle have any formal heritage protection today? Yes — on 17 November 1994, Spain's Ministry of Culture declared it a Bien de Interés Cultural, a designation for sites of special cultural significance.
