On the west side of the square, and built at the same time, is the Nadir Divanbegi Khanaka, a sufi cloister used for religious ceremonies, debates and instruction. Both this and the medressa opposite are named for Abdul Aziz Khan’s treasury minister, who financed them in the 17th century. It's the poor relation to the Nadir Divanbegi Medressa it faces across Lyabi-Hauz, but inside there's a worthwhile display of old photos, paintings and a model of Bukhara.
