The only surviving monument of the 18th century on Registan Square is the Bolo-Hauz complex. It includes a mosque with a multi-column canopy - ayvan - for public prayers, which was built by Emir Shahmurad with a detached minaret and the most ancient part of this ensemble - Bolo-hauz. The word Bolo-house means a children's pool. The construction period dates back to 1785-1800..
Bolo-hauz is a festive mosque, which was often visited by the rulers of Bukhara. The complex includes: a summer mosque and a winter mosque hidden by it, in front of which a pool is spilled. The stone winter mosque and hauz were built in 1712. The inner walls of the mosque are decorated with red and blue painting with carvings and a lot of gilding. All this created an atmosphere of lightness and festivity.
The summer mosque was built much later. This is an aivan with galleries and columns that surrounds the winter mosque on three sides. The sloping wooden roof is anchored on tall columns that stand on concrete foundations and are beautifully reflected in the pond. The unique paintings and carvings that adorn the columns make them varied and very elegant. The central entrance to the winter mosque is especially beautiful.
