Castle of les Espases Monument · Esparreguera, Baix Llobregat, Barcelona A castle on a rocky ridge running across the Llobregat, in the Cairat gorge, in Esparreguera; Count Borrell sold it to his loyal follower Guillem, of the Gurb-Queralt lineage, at an imprecise date between 966 and 985, and in September of that year Guillem donated it, together with that of Esparreguera, to the see of Vic, whose lords kept it until it passed to the Cardona family at the end of the 12th century. Today only part of a half-tower or bestorre survives, probably from the 10th century, along with a wall that follows the contour of the rock. Beside it stands the chapel of Sant Salvador de les Espases, the castle's former chapel, documented since the 14th century although with a 12th-century Romanesque wall and a 16th-century renovation; its roof suffered a partial collapse on 27 May 2024.
