Lyabi-Hauz (lit. 'brim of a pool') is very popular among tourists. It is the largest artificial reservoir of medieval Bukhara. It was made in about 1620 between Khana-ka and Madrasah, constructed by the order of khan's vizier Nadir Divan-beghi. The two new buildings and Kukeldash Madrasah formed a perfect architectural ensemble with the reservoir in the center. The pool is 42 meters long, 36 meters wide and about 5 meters deep. Lyabi-Hauz's 'banks' are equipped with stone steps by which Bukhara watermen went down to take some water.
