Castle of Casasola

Castle of Casasola is a crumbling medieval ruin perched on a rocky outcrop above the Tajuña river valley, a short distance from the town center of Chinchón in the Community of Madrid. Little remains beyond weathered walls and the stump of a tower, but the setting alone makes it worth the detour — the fortress seems to grow straight out of the rock, making it one of the region's most striking, if still fairly obscure, historic sites.

How do you get there?

The castle sits outside the built-up part of Chinchón, on private land that once formed the Casasola estate. The easiest approach is by car along the local road running through the Tajuña valley — roughly ten to fifteen minutes from Chinchón's main square. The final stretch has to be covered on foot, along a path climbing the escarpment. Sturdy shoes are worth packing, since the ground is uneven and the site itself has no visitor infrastructure: no parking area, no signage, no ticket booth.

What's the history behind it?

The fortress was built in the first half of the 15th century on the initiative of Juan de Contreras "the Elder," a Castilian knight from Segovia who acquired the land and set out to build a family seat there. It started life as a defensive stronghold, but like many similar castles in the region, it gradually took on a more residential character over time.

In 1583 the estate passed to the Arias Dávila family, Counts of Puñonrostro, who in 1684 were granted the title of Marquises of Casasola by the crown — permanently tying the castle's name to the family's aristocratic title. The site also has a footnote in 19th-century Spanish history: it's said to have hosted politicians and military figures involved in the events surrounding the proclamation of Alfonso XII as king in 1874.

What will you actually see?

Casasola today is a genuine ruin — sections of perimeter wall and the remains of a tower, partly fused with the rocky outcrop the castle was built on. There's no restored interior and no museum display; the draw is the raw, untamed character of the place and the sweeping view over the Tajuña valley below. It's a spot appreciated mostly by landscape photographers and regional history enthusiasts rather than mainstream tourist crowds.

The castle holds official heritage status as a Bien de Interés Cultural, giving it legal protection under Spain's 1985 historic heritage law — even though it continues to physically deteriorate. In recent years the property has occasionally been listed for sale together with the surrounding land, a reminder that this is a privately owned, partly neglected ruin rather than a formally managed monument.

When is the best time to visit?

Spring and autumn offer the most comfortable conditions, when temperatures around Madrid are milder and the ground around the castle isn't baked dry by summer heat. In summer the exposed hillside can get very hot with almost no shade, making the climb harder going. Early morning also brings the best light for photos, when the rocky spur and its ruined walls stand out sharply against the valley below.

Frequently asked questions

Is there an entrance fee? No, there's no official ticket booth or fee — but the land is private, and access to the ruins themselves can be restricted because of their condition.

Can you go inside the castle? Given how deteriorated the structure is, going inside isn't recommended and in places isn't possible — most visitors view the castle from the outside.

Are there other attractions nearby? Yes, Chinchón itself is one of the most picturesque towns in the Madrid region, known for its distinctive Plaza Mayor and the vineyards scattered around it.

How long does a visit take? A visit to the castle usually takes 30-45 minutes, including the walk up the path and time to take in the ruins and the valley view.
