Moorish architecture is visible in the cobbled streets and houses of the old town. The castle dates from the 13th century. While resting on Roman fortifications, the castle was rebuilt by King Dinis (Denis) in 1310. The most significant aspect of the castle is the imposing Torre de Menagem, now the symbol of the city of Beja, with its battlements and narrow walkway running around the tower. Inside, there are three floors featuring ogival doors and worked vaults. The castle now houses a small military museum.
