Castell del Baró de les Quatre Torres in la Morera de Montsant is a castle documented since 1011 that was substantially transformed into an elegant residential manor house during the late 18th and 19th centuries. Named for its distinctive towers, the structure features twin rectangular towers covered with ceramic tile and finished stucco, alongside a shorter hexagonal tower. Its ownership evolved through prominent Catalan families including the Claramunt, Requesens, and Montserrat lineages, reflecting centuries of regional power dynamics. Restored for social and cultural uses, the castle exemplifies the evolution of medieval fortifications into refined residential dwellings across Catalonia's noble estates.
