The Skifa Kahla of Mahdia

The Skifa Kahla, also known as Bab Zouila, is a 10th-century fortification. This structure is one of the few remnants of Mahdia’s ancient walls in Tunisia. The Fatimids built this fortress to protect access to the city. The fort is one of the rare vestiges of the old ramparts. It also serves as one of the access points to Mahdia’s historic center.

The Skifa Kahla of Mahdia, Fatimid fortress and Ottoman modifications

The construction of the building dates back to 916. The Mahdi ordered its construction. The design reflects Fatimid architecture. In the 11th century, modifications adapted the building for Turkish-made artillery. The builders also added halls and storehouses for arms and ammunition. The building survived the siege of Mahdia by Emperor Charles V.

For a time, this fort was the only land entrance to Mahdia. It served as a defense against Christian invasions and imperial wars. According to historians, the name “Skifa Kahla” means “Dark Vestibule.” In 1554, a group of Spaniards blew up the entrance. After these attacks, the building underwent several modifications. At the end of the 16th century, the Turks rebuilt the wall system. Skifa Kahla then served as the main tower for the city’s second line of defense.

The tower rises 18.5 meters high. It has a depth of 12.70 meters and a width of 12 meters. A corridor leads to the markets of the ancient city. This corridor features 6 iron gates. Two polygonal projections date from the 17th century. The structure includes an archway divided into sections by loop gates and a portcullis. In 2015, the Tunisian National Heritage Institute carried out concrete restorations. These renovations commemorated the 1200th anniversary of Mahdia’s founding. Ultimately, the Skifa Kahla offers a fascinating glimpse into Tunisia’s medieval history.
