Crowning the highest hill above Alfama and the Tagus, São Jorge Castle is the most visible monument in Lisbon's skyline and one of the oldest. The site has been continuously occupied for nearly three thousand years — a Phoenician trading post, then Roman, Visigothic and finally an Islamic citadel that the Moors fortified between the 11th and 12th centuries. After a three-month siege in 1147, King Afonso Henriques, helped by a small army of Crusaders heading to the Holy Land, captured the castle from the Almoravids and made Lisbon the capital of a young Christian kingdom.
Today the complex covers about six hectares and includes the medieval citadel with its eleven towers and walkable ramparts, a large hilltop garden where peacocks, geese and ducks roam freely, an archaeological site preserving Iron Age, Roman and Islamic layers, and a small museum with finds from the digs. Inside the Tower of Ulysses, a Camera Obscura projects a live 360° view of Lisbon onto a parabolic mirror — one of only a handful in Europe still operational.
Pair the visit with a stroll through Alfama, a pastel de nata at Pastelaria Alfama Doce, and the climb back down past the Sé Cathedral to the Baixa.

History & context
The hilltop has been fortified since the Iron Age, but the castle that stands today owes its layout to the Islamic period (8th–12th centuries) when Lisbon, then known as al-Ushbuna, was the western frontier of al-Andalus. In October 1147, after a three-month siege described in the chronicle De Expugnatione Lyxbonensi, King Afonso Henriques took the citadel with the help of Crusader fleets. It became the royal residence until the 16th century, when the court moved down to the riverside palace destroyed in the 1755 earthquake. The castle was renamed in honour of Saint George — patron of knights and of England — by King João I in 1378, sealing his alliance with the English crown.
