The complex that Sultan al-Muayyad built is situated next to Bab Zuwayla in Cairo, and originally contained a madrasa-khanqah, a Friday mosque, and two mausoleums. It was constructed between 1415 and 1422 AD. However, unlike Barquq's madrasa-khanqah, in which the Sufis of the khanqah and students of the madrasa dwelt under the same roof and enjoyed exposure to each other's teachings and religious practices, this madrasa, whose curriculum comprised the study of official religion according to the four rites, was dedicated to Sufis only.
Because of it's site, the mosque, or at least it's minarets, became a land mark of Cairo. Originally, the site had unpleasant connotations, because there was a prison adjoining Bab Zuwayla which al-Mu'ayyad, when an amir, was lucky to leave alive.
Originally, the mosque had three minarets, including the two we see above the towers of Bab Zuwayla. They are twins, but the third one, near the western entrance, was different in appearance. However, it was destroyed sometime during the 19th century. The two remaining ones, though they present no innovation in the evolution of minarets, are particularly slender and elegant with their zigzag carved shafts. The carved chevrons decorating the octagonal second stories of the twin minarets, which are also to be seen on the exterior of the stone dome, provide an excellent example of this type of surface decoration for carved masonry domes from this period. Noteworthy, however, is the signature of their architect, carved on a cartouche above the entrance to their staircases on the northern side of each shaft and dating to 1419 and 1420 (AD). His name was al-Mu'allim Muhammad Ibn al-Qazzaz and thus far, this is the only known signature of a Mamluk architect on a building. We do not know to what extent he was involved in building the rest of the complex, but he exploited the mosque's proximity to Bab Zuwayla by using it's towers as both buttresses and bases from which the two identical minarets rise.
