Case File Overview
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.
Historical Background
The original foundations of Borj El Kebir were constructed around 1289 AD under the orders of Roger de Lauria, the Aragonese Admiral who conquered Djerba island for the Crown of Aragon. Built as a rectangular stone stronghold directly overlooking the Mediterranean waters, the fort was designed to secure Christian rule and control maritime trade routes along the North African coast. In 1450, local Hafsid ruler Sultan Abu Faris Abd al-Aziz II captured and expanded the fortress, converting it into a primary Islamic coastal bastion.
The most dramatic and bloody chapter in the fort's history occurred in May 1560 during the monumental Battle of Djerba. A Spanish imperial fleet under Juan de la Cerda seized the fort, garrisoning over five thousand soldiers inside. However, Ottoman corsair admirals Dragut Reis and Piyale Pasha launched a relentless siege, surrounding the fort by sea and land. After weeks of fierce fighting and water deprivation, the Spanish defenders surrendered. The Ottoman forces executed the surviving Spanish garrison and erected a horrifying monument outside the fort walls known as Borj al-Rous (Tower of Skulls), composed of thousands of human skulls and bones bound in mortar, which remained standing until 1848.
In the late sixteenth century, Ottoman Governor Ghazi Mustapha Bey extensively rebuilt the fortress into its modern form, adding heavy gun emplacements, subterranean magazines, and reinforced battlements. The fort remained an active military post through the French protectorate era until being designated a national historical monument. Today, managed by the National Heritage Institute, Borj El Kebir draws thousands of tourists who walk its high sea ramparts and learn about its dark pirate past.
Legends & Curses
The gruesome history of the Battle of Djerba and the Skull Pyramid has spawned persistent island legends regarding pirate curses, trapped souls, and sea spirits. Local Djerban oral traditions recount that Dragut Reis placed a powerful maritime curse upon the fort, decreeing that the spirits of the fallen Spanish soldiers would remain bound to the stone walls until the oceans dried up. It is widely believed that spirit guardians known as Jinn haunt the subterranean dungeons, guarding gold plunder buried by Barbary corsairs beneath the stone floor. Island elders insist these subterranean entities feed on human fear, causing deep disorientation, sudden nausea, and panic in visitors who venture alone into unlit storage cellars without carrying traditional protective amulets.
Another widespread legend concerns the exact spot where the Skull Pyramid stood for nearly three centuries before being dismantled in 1848 for proper Christian burial in the Catholic cemetery of Houmt Souk. Local storytellers warn that on foggy nights when sea mist rolls over Houmt Souk port, phantom silhouettes of Spanish soldiers wander the beach searching for their missing bones. Island elders advise fisherman never to moor their boats near the sea wall after midnight, claiming that ghostly hands reach up from the dark water attempting to pull living souls under, dooming them to wander the sea floor for eternity alongside sunken corsair galleys.
Reported Phenomena
Tourists, local night watchmen, and fishermen near Borj El Kebir report frequent supernatural occurrences along the ramparts and surrounding beach. The most commonly reported phenomenon involves auditory hallucinations, including distant canon fire, clashing iron swords, loud metallic thuds, and guttural Spanish moans echoing from the subterranean dungeons beneath the central courtyard. Many visitors report experiencing abrupt, icy sea breezes, oppressive feelings of cold air, and sudden chest pressure inside windowless internal chambers during scorching summer days.
Photographers frequently document glowing light spheres, white spectral shapes hovering along the seaward battlements, and shadowy figures wearing 16th-century helmets standing on the upper parapets at twilight. Local security guards report hearing heavy iron doors slamming shut in sealed storage rooms, as well as distinct footsteps marching along stone walkways when the fort is completely empty. Feelings of intense, unaccountable dread, sudden panic, and claustrophobia are commonly felt near the spot where the Skull Pyramid once stood.
Architecture & Layout
Borj El Kebir is a massive rectangular fortress constructed from dense sea-stone, mortar, and local limestone, surrounded by a deep dry moat. The exterior walls rise over ten meters high, featuring heavy corner bastions, cannon embrasures, and arrow slits designed to defend against naval bombardments and land sieges. A single stone bridge spans the outer moat, leading into a heavily defended entrance gateway fitted with double iron gates and murder holes.
Inside the fortress lies a vast central parade ground flanked by vaulted troop quarters, stables, ammunition storehouses, and a small historic mosque built for the Ottoman garrison. Beneath the courtyard floor sits a complex network of subterranean cisterns and gloomy prison dungeons where captured sailors were held. The high rampart walkways offer unobstructed panoramic views of the Mediterranean Sea and the Houmt Souk fishing harbor, showcasing the fort's strategic maritime command.
