Built in 1267, this former Koranic school is today used as a mosque. Its high, forbidding walls are reinforced at each corner by buttresses that give the building the appearance of a fortress. The portal, with its simple Gothic arch, is rather plain in style, with the traditional muqarna decor featuring only around the two small windows on either side of the doorway. A türbe (tomb) adjoins the medersa, crowned with a superb octagonal brick dome lined with a band of blue faience. The nearby Torumtay Türbesi houses the tomb of the medersa's founder, who died in 1276.
