With a central dome and cupolas dominating the four corners of the prayer hall square, it is highly influenced by Ottoman architecture. It is the only domed mosque in Tunis. Turkish in inspiration, it is similar to Sainte-Sophie, the mosque of Sultan Ahmed in Istanbul and the Pecherie in Algiers.

The prayer room is constructed on a square plan and surrounded on three sides with galleries overhanging three U-shaped courtyards. The galleries are supported by marble columns with Turkish-style capitals decorated with acanthus leaves on the sides and scrolls at the corners. Inside, four robust 1.50 m wide pillars support a hemispherical dome on pendants which rises to 29 m above ground level. The dome rests on two superposed drums, one circular and the other octagonal. This central dome is supported by 4 semi-domes. At the corners of the hall, the roof is completed by four little domes placed on circular drums. Viewed from the exterior, the mosque is a collection of domes.

Polychrome tiles were brought from Iznik (Turkey) to cover a significant portion of the wall facing Mecca and the magnificent pillars that support the central dome. In the 1960s, the mosque’s interior underwent renovation.
