The Great Mosque of Mahdia was built in the 10th century. Located on the southern part of the peninsula that housed the old city, construction began in 916, when the city was founded by the Fatimid caliph Abdallah al-Mahdi, to serve as the main mosque of the new city. The current mosque was largely reconstructed by archaeologists in the 1960s, with the exception of the preserved entrance facade.
