This photo was taken at Po-i-Kalyan (also Poi Kalyan), which means "The foot of the Great", and which belongs to the architectural complex located at the foot of the great Kalyan minaret in Bukhara, Uzbekistan. The complex is located at historic part of a town. Since 713 several ensembles of main cathedral mosques were built at this area to the south of the Ark citadel. One of these complexes, burnt out by Genghis Khan during the siege of Bukhara, was built in 1121 by the Karakhanid ruler Arslan-khan. The Minaret Kalyan is the only of structures of Arslan-han complex, which was kept safe during that siege.
