Built in the 17th century in response to the Restoration Wars with Spain, the Fortress of St. Sebastian turned the old medieval castle into the most important military garrison in the Algarve, particularly in light of its strategic location next to the border. The design of the fortress consists of an irregularly-shaped walled enclosure with five bastions.
