Castle of Chiriveta

The Castle of Chiriveta is an 11th-century Romanesque watchtower perched above the Monrebey gorge in the municipality of Viacamp y Litera, in the heart of the Ribagorza region of Aragón (Huesca province). It stands on a hill near the abandoned settlements of Chiriveta and Mongay, at an altitude of 671 metres, and for centuries kept watch over the routes running alongside the Noguera Ribagorzana river.

What will you see there?

The centrepiece is a cylindrical tower roughly 3.5 metres in diameter and about 15 metres tall, built directly on a solid rock base. Its walls are up to 2.15 metres thick, which explains why the structure has survived in such good condition for nearly a thousand years. Originally the tower had at least four floors, and its arched openings were designed to hold timber defensive structures — a form of projecting wooden hoarding used by defenders. The surrounding curtain wall and moat no longer stand in full, but traces of the old fortifications are still visible around the base.

The castle is dated to around 1070 and is considered one of the last of its kind built in the region. It already appears in written records from 1077, while the settlement of Chiriveta itself (Girbeta in Ribagorzan Catalan) is documented from 1089 onward. The land once belonged to the county of Pallars Jussà, though local rule was held in fief by the Girbeta family. Later the area became part of the fourth county of Ribagorza, and until the end of the Ancien Régime it belonged to the barons of Espés-Alagón. Unlike earlier fortresses in the region, Chiriveta was not built to withstand sieges — its role was surveillance over already-conquered land and control of trade routes rather than active defence.

How do you get there?

The starting point is the village of Chiriveta, reached via a signposted turn-off from the N-230 road, followed by a forest track toward El Mas. It's best to leave the car at the village and cover the rest on foot — the route forms part of the marked trail PR-HU 206 (Ermita del Congost – Castillo de Chiriveta). The full walk takes about 55 minutes: the first 40 minutes lead to the Virgen del Congost hermitage, with a further 15-minute climb to reach the tower itself. The path is well marked and opens onto broad views over the Ribagorza valley along the way.

What else is worth combining with the visit?

On the way you pass the Virgen del Congost hermitage, a small chapel set into the gorge landscape that makes a natural stop during the climb. Nearby lies the abandoned hamlet of Mongay, which gives the castle its alternative names — the Tower of Mongay or the Tower of the Moors. What draws visitors here above all is the silence and isolation: with few crowds, the walk to the tower feels like a genuine journey into the history and landscape of Ribagorza.

When should you visit?

Given the mountainous terrain, lack of shaded shelters, and long exposed stretches, spring and autumn are the best seasons, offering milder temperatures and clearer views. In summer, an early morning start is recommended to avoid the heat on the unshaded sections of the trail.

Frequently asked questions

How long does it take to reach the Castle of Chiriveta? The full route from the village of Chiriveta takes about 55 minutes one way: roughly 40 minutes to the Virgen del Congost hermitage, followed by another 15 minutes up to the tower itself.

Can you climb inside the tower? The tower survives mainly as an exterior shell — the original floors and timber defensive elements are gone, so the visit is essentially about viewing the structure from outside and examining the remaining foundations.

Where does the castle's name come from? The building is also known as the Tower of Mongay or the Tower of the Moors, named after the nearby abandoned settlement of Mongay and its former role guarding the trade routes below.

Is the trail suitable for children? It's a moderately demanding mountain path with a total walking time of about an hour, so it should be manageable for children used to hiking, provided you bring water and sturdy footwear.
