Borj Ghazi Mustapha also called Borj Elkebir : This defensive monument was built in 1289 by Roger de Loria, admiral of Aragon and Sicily, on the site of a Roman fortification whose vestiges were reused in the construction of the fort. The latter was remodelled in the XVth century, reinforced in 1557 by Dragut and given its present configuration by a Spanish garrison of 6000 soldiers who came in 1560 to chase the Turkish pirates from the island before being exterminated in the same year by the Turkish pirate.
