The mosque’s famous square minaret, which rises to a height of 38 meters and was modeled after those erected by the Almohads in North Africa and Iberia, is also accessible from the mosque’s main entrance.

A portion of the Mansourah Castle is included in it. The mosque was established around 1303 by Sultan Abu Yakub, according to archaeological findings about its design, and Abu al-Hassan decorated its main gate in 1336. There are 13 doorways inside the yard, all of which are walled off, and there is a sahn in the center with a fountain. Three passageways encircle the sahn, and they have the same tilework as the prayer hall. The prayer room is immediately connected to the sahn and features tilework resembling the qibla wall, which is also present in Samarra’s Baybars Mosque from the 13th century.

The mosque occupies a rectangle 60 m wide and 85 m long. The main door opens at the base of the minaret, which protrudes from the middle of the north-western side. The square courtyard, which is typical of Maghrebian mosques of the 13th and 14th centuries, is 30 meters on each side and was framed by galleries extending the aisles of the prayer room. The latter was occupied by thirteen naves divided into six bays by onyx columns 0.44 m in diameter

The mihrab, a niche with cut sides, was surrounded by a room for the dead similar to that found in the Quaraouiyine of Fez. In addition to the main entrance, two doors built of stone, protruding on all four sides, gave access to the mosque.

The minaret, although disconnected from its lantern, stands at 38 m. A small door opening into the mosque, under the front gallery of the courtyard, gave access to the ramp which, by seven revolutions around the central core, went up to the level of the upper gallery. This ramp was lit by large openings in the middle of the four sides and by smaller openings in the axis of the ramps. The 1.50 m thick walls are made of pink siliceous stone.
