Moorish Castle (Castelo dos Mouros)

The Moorish Castle (Castelo dos Mouros) is a hilltop fortification on the Serra de Sintra in Sintra, Portugal, overlooking the town and the Atlantic coast. It was built by the Moors, probably in the 8th to 10th centuries, during the period when much of the Iberian Peninsula was under Muslim rule, as a lookout and defensive base for the settlement below. In 1147, after the conquest of Lisbon, King Afonso Henriques took the castle from its Moorish defenders, reportedly after a peaceful surrender, and it passed to Christian control. A small Romanesque church dedicated to São Pedro de Canaferrim was built within the walls in the 12th century and its ruins remain. The castle lost its military use over time and was badly damaged by the 1755 earthquake. In the 19th century Ferdinand II, who was creating the neighbouring Pena Palace and Park, ordered restoration of the walls, towers and paths and added romantic touches such as pine and cork trees planted along the ridge. The castle is roughly 450 metres above sea level. What remains is a long, crenellated curtain wall that climbs and drops along the rocky ridge, linking two main groups of towers, with a cistern of Moorish origin, rock-cut tombs, and stone stairways. The castle is an archaeological ruin and landscape rather than a museum, so there is little interior display, and the experience is a walk along the ramparts with views toward Pena Palace, the Palace of Sintra and the coast. A second restoration programme in the early 21st century stabilised the walls and improved the footpaths. It is part of the Sintra Cultural Landscape World Heritage Site, inscribed by UNESCO in 1995.
