Castelo de São Jorge

Perched on Lisbon's highest hill, this medieval fortress encloses nearly three thousand years of continuous settlement within a single ring of walls. Its definitive form took shape under Moorish rule from the 8th century, when it served as the Alcáçova — the palace-citadel of Islamic Lisbon. In 1147, Afonso Henriques, Portugal's first king, seized the castle with the help of northern European crusaders in a siege still considered the founding moment of the Portuguese state. The royal court resided here into the 16th century before the great earthquake of 1755 collapsed significant sections. Today restored walkways connect twelve towers, and an on-site archaeological dig displays Phoenician, Roman, Moorish, and medieval finds side by side. The battlements offer one of Lisbon's most expansive views across the Alfama rooftops to the Tagus estuary, at its best in the long hour before sunset.

11th-century hill fortress, 11 towers, free-roaming peacocks and 360° views over the city and Tagus.
