Kairouan (Arabic: القيروان Qeirwān, also known as al-Qayrawan), is the capital of the Kairouan Governorate in Tunisia. It is a UNESCO World Heritage site. The city was founded by the Umayyads around 670. In the period of Caliph Mu'awiya (reigned 661–680), it became an important centre for Sunni Islamic scholarship and Quranic learning, and thus attracting a large number of Muslims from various parts of the world, next only to Mecca and Medina. The holy Mosque of Uqba is situated in the city.
