Castelo de São Jorge: St George’s Castle
Standing high above Alfama, Castelo de São Jorge is one of Lisbon’s most recognisable landmarks. Its walls, shaded courtyards and broad views over the city and the Tagus make it a rewarding place to explore Lisbon’s past.
The hill was occupied long before the medieval castle took shape. The fortifications visitors see today have their origins in the Moorish period, with substantial changes and restoration over the centuries.
From Moorish Stronghold to Royal Residence
In 1147, Portugal’s first king, Afonso Henriques, captured Lisbon with the help of northern European crusaders during the Second Crusade. The castle’s surrender followed a prolonged siege and marked an important moment in the Christian conquest of territory on the Iberian Peninsula.
The castle and the adjoining royal palace, known as the Paço da Alcáçova, became a centre of royal life. Portuguese monarchs used the palace before the court moved to a new residence beside the river in the early sixteenth century.
The 1755 earthquake caused serious damage, and the complex also underwent changes during its long use by the military. Extensive restoration in the late 1930s and early 1940s shaped much of its present appearance. What you see today reflects both its medieval history and later efforts to recover that character.
What to See Inside the Castle
Courtyards and Views Across Lisbon
The entrance leads towards the Praça de Armas, an open area with a statue of Afonso Henriques among the trees. Take time here to enjoy the panorama: rooftops tumble down towards the river, offering a sense of how Lisbon grew around its hills.
Gardens and traces of the former royal palace lead towards the fortified enclosure. The grounds are worth exploring slowly, rather than treating them simply as a route to the battlements.
Walls and Towers
The castle’s defensive walls connect eleven towers. Accessible sections of the battlements offer changing views over the grounds and the surrounding city. Expect steps and uneven surfaces, and take care on the higher walkways.
Among the towers is the Torre de Ulisses, or Tower of Ulysses, associated with the royal archives once kept here. Its camera obscura uses mirrors and lenses to project live views of Lisbon onto a viewing surface. Access to this experience can depend on conditions and availability, so check the arrangements when you visit.
Archaeological Discoveries
The archaeological site reveals layers of occupation reaching back to the Iron Age, alongside remains from the Moorish period and later buildings. Finds unearthed within the complex help tell the story of the people who lived on this hill long before it became a visitor attraction.
Check current access arrangements for the archaeological area before planning your visit around it, as these may differ from access to the wider castle grounds.
The Legend of Martim Moniz
The Moniz Gate is linked to one of Lisbon’s best-known siege legends. According to the story, Martim Moniz sacrificed his life by holding a closing gate open with his body, allowing Christian soldiers to enter in 1147. It is best understood as a local legend rather than an established account of the conquest.
Planning Your Visit
The approach through the old streets is part of the experience, but it involves uphill walking and uneven paving. Wear comfortable shoes and allow time to pause along the way. If you prefer to reduce the climb, consider a local bus or taxi for part of the journey.
Before setting out, check the castle’s official visitor information for current tickets, opening times and access to individual attractions. The grounds and ramparts have different physical demands, so visitors with reduced mobility should also check accessibility details in advance.
