Castell de Burriac is a 12th-15th-century medieval castle perched dramatically on a 400-metre hill near Cabrera de Mar, overlooking the Mediterranean coast and Maresme plain. First documented in 1017 as a watchtower, the castle's well-preserved circular base tower and strategic location made it crucial for regional defense and territorial control. The ruins offer exceptional panoramic views spanning from Vilassar to Caldes d'Estrac and across the sea. Popular with history enthusiasts and hikers alike, the castle is accessible via a scenic 45-minute walk from the town, featuring hiking trails that showcase both medieval architecture and natural coastal landscape.
