The castle features a 'Camera Obscura' that uses a system of lenses and mirrors to project real-time views of Lisbon onto a white dish.
Excavations inside the castle walls uncovered the ruins of an 11th-century Moorish residential neighborhood buried by the 1755 earthquake.
The castle served as the site where King Afonso I first entered the city during the 1147 Siege of Lisbon, ending Moorish rule.
The Torre de Menagem, the strongest tower of the castle, was used as a royal archive for storing kingdom records during the Middle Ages.
The castle grounds are home to a colony of free-roaming peacocks that are considered a local symbol of the site.
The fortress was strategically located to oversee the entire Tagus estuary, making it the primary defensive node for Lisbon for centuries.
Castelo de São Jorge is a fortified Moorish citadel occupying the highest hill in Lisbon, offering panoramic views of the city and the Tagus Estuary. The site contains a medieval royal palace, a residential quarter for the elite, and a perimeter wall featuring eleven towers. It served as a royal residence from the 12th century until the early 16th century, when the monarch moved to the Ribeira Palace. The current structure incorporates remnants of various periods, including Iron Age, Phoenician, Roman, and Visigothic strata revealed by archaeological excavations. Visitors can walk along the defensive walls and explore the keep, known as the Torre de Menagem. The grounds house a permanent archaeological site and an exhibition of objects from the 7th century BC to the present day. A camera obscura located in the Torre de Ulisses provides 360-degree real-time projections of the city. The site is actively managed and remains fully open as a major historical landmark in the Alfama district.
