Al-Zaytuna Mosque (Arabic: جامع الزيتونة, romanized: Jāmiʿ al-Zaytūnah, lit. 'Mosque of the olive') is a major mosque at the center of the historic medina of Tunis, Tunisia. The mosque is the oldest in the city. It was founded at the end of the 7th century or in the early 8th century, but its current architectural form dates from a reconstruction in the 9th century, including many antique columns reused from Carthage, and from later additions and restorations over the centuries.
The mosque developed into a place of higher education, today the University of Ez-Zitouna, which became the most important educational institution in Tunisia from around the 13th century onward. Ibn 'Arafa, a major Maliki scholar, al-Maziri, the great traditionalist and jurist, and Aboul-Qacem Echebbi, a famous Tunisian poet, all taught there, among others.
