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.

Frequently Asked Questions
Everything you need to know before visiting
The Skifa Kahla, which means "Dark Vestibule" in Arabic, is a monumental Fatimid gateway built in 916 CE as the sole landward entrance to the fortified peninsula city of Mahdia, the first capital of the Fatimid caliphate.
The gateway was built by the Fatimid caliph Obeid Allah el Mahdi as part of a comprehensive defensive system protecting Mahdia on its narrow land approach. At one time, six iron doors secured the passage.
The gateway stands 18.5 metres high, is 12.70 metres deep, and 12 metres wide, with a barrel-vaulted corridor running through its full length. It is one of the best-preserved Fatimid military structures in the world.
The gateway underwent significant restoration work in 2015 to consolidate the masonry and improve visitor access. Despite the restoration, the structure retains much of its original Fatimid character.
Just beyond the gateway lies the medina of Mahdia with its Fatimid mosque, the Borj el Kebir Ottoman fort, the fishing harbour, and a clifftop promenade overlooking the sea. Mahdia's beaches and seafood restaurants are also nearby.
Mahdia is about 200 kilometres south of Tunis. A direct train line connects Tunis to Mahdia via Sousse. The Skifa Kahla is at the entrance to the old medina, the first landmark visitors encounter when walking from the new town into the historic centre.
