The medieval frontier castle and seat of the Barony of Orcau

The Castell d'Orcau, a historical castle located in Isona i Conca Dellà, served as the seat of the Barony of Orcau in Pallars Jussà. Situated on a hill 887 meters above sea level, the castle's position allowed for extensive control over the territory, overlooking both the Conca de Tremp and the Conca Dellà. It is a building declared a cultural heritage of national interest.

To reach the site, one must follow the C-1412 road connecting Isona with Tremp. From the turnoff toward Figuerola d'Orcau, the path leads to Orcau, where a winding path descends 154 meters to reach the upper part of the village. Due to its strategic positioning, the castle is inaccessible from the south and the west.

Built around the turn of the millennium, the castle served as an important logistics and military center. It facilitated the cultivation of land in the surrounding basins and functioned as a border castle between the domains of the county of Pallars and those of Arnau Mir de Tost. The architecture features a double walled enclosure with remains of circular towers and a square plant with semicircular corner structures.

The site also contains the remains of a Romanesque church dedicated to the Mare de Déu de la Pietat. Fragmentary mural paintings from the apse, representing apostles on a colored background with landscape elements, are preserved today at the Museu Nacional d'Art de Catalunya.
