[3] Salem Ben Yagoub [fr] confirms that Tajdit was built on the orders of the Rustamid State.
According to Ben Yagoub, the madrasa developed as soon as the mosque was created, and there used to be structures around the place of worship to accommodate lessons, students, and teachers, as evidenced by mounds of earth still around the area.
[clarify][4] According to R. Mrabet, the study of the building establishes that it underwent a significant modification in a distant era; the prayer hall was then much smaller than it is today, and the north arcade, which still bears traces of decoration, would belong to this original core.
Surrounded by an open courtyard and various annexes, the mosque boasts massive white walls and sturdy protruding buttresses, evoking the appearance of a fortress.
A square minaret, situated in the northeast corner of the prayer hall, is crowned with a lantern in the shape of a small bulbous dome, it also houses a Quranic school.
