The great ramparts of this 16th-century fortification added the words do castelo to the town's name and protected it against attack from pirates eager to share in its wealth. It was completed during the reign of King Manuel I, which is why architectural details such as the Roqueta Tower are Manueline in style. These days the massive structure serves as a hotel, among other uses. A large market is held outside the castle walls every Friday.
