Borj El Kebir Fort
Borj El Kebir, also known as the Fort of Ghazi Mustapha, is a formidable coastal fortress standing along the northern shores of Djerba island at Houmt Souk. Built over 13th-century Aragonese foundations and heavily expanded by Ottoman corsairs, this seaside castle was the site of the infamous 1560 Battle of Djerba, where Ottoman forces led by Admiral Dragut slaughtered thousands of Spanish defenders and constructed the macabre Skull Pyramid (Borj al-Rous) outside its walls. Visitors and locals report hearing phantom battle cries, iron chains rattling in subterranean dungeons, and seeing ghostly corsair guardians on the seaward bastions.
