 The date of this tower is unknown and it pre-dates many other towers that were built around the Bay of Gibraltar and south of Algeciras as batteries and watchtowers.This tower was used by the Admiral Egidio Boccanegra in the 14th century during the Siege of Algeciras (1342-1344).The tower appears on a map of 1608 and it was improved after 1704 following the Capture of Gibraltar when the enclave was seen as a potential beachhead for British forces.
