Hegira 297 / AD 910, Fatimo-Zirid (Beginning of the dynasty)
Mahdiyya, Tunisia
The Great Mosque of Mahdiyya was built by the caliph al-Mahdi. It was modified on several occasions before being rebuilt by the French architect A. Lézine between 1961 and 1965. The mosque does not appear to have had a minaret, with the call to prayer being made from the top of one of its towers.
