Fort St Angelo

Fort Saint Angelo is a bastioned fort in Birgu, Malta, located at the centre of the Grand Harbour. Originally built in the medieval period as a castle known as the Castrum Maris, it was rebuilt by the Order of Saint John as a bastioned fort between the 1530s and the 1560s. The fort served as the Order's headquarters during the Great Siege of Malta in 1565. A major reconstruction to designs by Carlos de Grunenbergh took place in the 1690s, giving the fort its current appearance and making it one of the most formidable structures on the harbour.
