Castell de Mas Carbó is a medieval castle ruin located on the highest hill in Palafolls, Barcelona, with documented origins dating back to at least 1252 when it was part of a defensive chain of fortifications in the Selva region. Built during the Middle Ages to protect territorial interests, the castle features a multi-storey structure whose height and remaining walls suggest substantial original construction. Though largely crumbled over the centuries, visitors can still observe an intact chapel, storage areas, and extensive stairways indicating multiple floors. Opened to the public in the 1920s, this castle offers a compelling glimpse into medieval Catalan architecture and frontier defense strategies.
