The 11th-century Castell de Sant Gervàs

In the Pallars Jussà region, hidden amidst the rugged beauty of the Montsec de Rúbies massif, lies a relic of a bygone era: the Castell de Sant Gervàs. This castle is a testament to the strategic importance of this region, which served as a border with the Muslims of Lleida until the mid-11th century.

Excavated between 1978 and 1980 by the Department of Medieval History of the University of Barcelona, the archaeological site includes a castle from the 11th century, complete with a tower mestra and a precinct with bestorres. Within the precinct, the abandoned village of Sant Miquel de la Vall was enclosed within its own wall. The village contained various houses of rectangular plan, including the house rectoral, and is included in the Inventari del Patrimoni Arqueològic i Paleontològic de Catalunya. At the site's eastern end, the remains of the Romanesque church of Santa Maria del Castelló Sobirà can still be seen.

The castle's layout resembles that of the castell de Mur, with well-cut, regularly arranged stones making up the walls. The tower mestra, or homage tower, is found in the middle of the eastern wall, with three bestorres also present. While only the foundations and first rows of the walls of the village houses remain, archaeological excavations have revealed part of its composition, including remains of the plaza and streets. The surface of the castle, built with well-worked stone and a good mortar of lime and sand, is 1,269 m2.

The village of Sant Miquel was built in the 11th century, taking into account the border situation and the possible Islamic enemy. The castle and village were involved in feudal disputes until 1319, when Bord de Pallars bought them from the priorat for 6,000 sous jaquesos. Following the late 14th century, the valley was violently assaulted by the troops of the count of Foix and viscount of Castellbó, an event that likely influenced the final abandonment of the village.
