Castelo de S. Jorge, Lisbon — Visitor Guide & Things to Do Nearby

Castelo de Sao Jorge has been watching over Lisbon from its hilltop perch for so long that archaeologists have found evidence of human settlement here dating back to the 8th century BC. The hill has been fortified by Celts, Phoenicians, Greeks, Carthaginians, Romans, Visigoths, and Moors before the Portuguese finally took it. The castle in its recognizable form dates to the 11th century, when the Moors built the fortress to defend Lisbon during the centuries-long struggle between Christian and Islamic powers on the Iberian Peninsula.

The turning point came in 1147 during the Second Crusade, when King Afonso Henriques and northern European crusader knights conquered the castle in the famous Siege of Lisbon. This victory established Portugal as a Christian kingdom with Lisbon as its capital. The castle became the royal residence, and around 1300, King Denis extensively renovated it, transforming the Moorish alcacova into the Royal Palace of the Alcacova. Gothic and Manueline elements were added over the centuries, layering architectural styles like chapters in a history book.

Today the castle functions as an open-air museum where you can walk the ancient walls, explore courtyards, and take in what might be the most spectacular panoramic views in all of Lisbon. The Tagus River, the city's bridges, and neighborhoods stretching to the horizon unfold below you. Exploring the castle and the Alfama district with Questo transforms the climb from a workout into an adventure, with stories and challenges hidden along the medieval streets that wind up to the gates.
