Castell de Calaf sits prominently atop a hill in the town of Calaf, Barcelona province, and is designated a Cultural Asset of National Interest. First documented in 1015 during its construction, this fortress served as a vital frontier defence along the Hispanic March, controlling crucial trade routes between northern Catalonia and central regions. The castle commanded views over the surrounding plain where north-south and east-west communication routes intersected. Built on a polygonal plan similar to nearby Mirambell Castle, Calaf remained significant through the medieval period, passing to Viscount authority in 1318 and later becoming part of the County of Cardona in 1375, making it one of the region's most important fortifications.
