[1] Located on the outskirts of the city overlooking the sea, near the Ribat of Monastir, the mosque is characterized by the high exterior facades built of stone, frames surrounding the windows and doors, as well as arches that extend along the mihrab.

The present mosque, which has undergone enlargements and additions over the centuries, includes a prayer room and a minaret, and doesn't have a courtyard inside.

In the course of the 11th century, an enlargement of the room to the south-east was accompanied by the addition of columns surmounted by arched vaults.

In the Hafsid era, expansion work continued with the construction of a square-based minaret and the addition of two naves in the north-western part.

One of the peculiarities of the Great Mosque of Monastir consists in the absence of a dome surmounting the mihrab, which is rather rare in medieval Ifriqiyan architecture.
