Castle of Castellbisbal Monument · Castellbisbal, Vallès Occidental, Barcelona The Castell de Castellbisbal (Vallès Occidental, Barcelona), from which the municipality takes its name, is a medieval castle now very ruined: only a few foundation walls survive around the chapel of Sant Vicenç, on the hill of Garses. It is documented from 1013 as an episcopal stronghold under Bishop Guislabert, and around 1044 it was pledged to the Count of Barcelona following a political conflict. The Castellbisbal family served as castellans during the 12th and 13th centuries; Berenguer de Castellbisbal rebuilt it in the early 14th century. After the Catalan civil war of 1462-1472 it passed to the Requesens family, which consolidated its ownership around 1494. It was declared Bien Cultural de Interés Nacional (Spain's highest level of heritage protection) on 8 November 1988. Photo: Deosringas (CC BY-SA 3.0 es) What to see and do in Castellbisbal
