St. Philip's Castle
St. Philip's Castle (Catalan:Castell de Sant Felip, Spanish: Castillo de San Felipe, often known as Fort St Phillip) was a fortress guarding the entrance to the port of Mahón. It is located in the municipality of Es Castell, on the island of Minorca.
It was rebuilt by British forces in the 1760s, around an earlier Spanish fort, the Castell de San Felipe, which had been established about 1554. It is best known for its unsuccessful defence on two occasions by the British: during the Siege of Fort St Philip (1756) and the Invasion of Minorca, 1781. Following the latter event, the castle was partly demolished.
