The mosque is large and slightly irregular in its floor plan due to multiple expansions and modifications over the centuries. The mosque's mihrab and the ornamental arches near it are believed to date from its original construction, while the current courtyard and much of the north-east section of the mosque is of a later construction. Most of the mosque is of a simple construction in the same hypostyle form of other Moroccanmosques. A well-proportioned minaret, 24 meters high and with decorated facades, stands on the mosque's western side. The minaret was likely built or completed in 1317, a couple of decades after the mosque's foundation.
