There are a good few Buran around; there's one on display in Gorky Park, well known to visitors to Moscow. Some years ago they were charging a silly small fee to go round it.
15 Buran were built, in various incarnations. Five were actual space orbiters, but only one flew (unmanned) into space. Eight were used for ground work, one was a simulator, and one was a wooden mock-up. There is a third one somewhere at Baikonur besides these two. Only one of these is orbiter standard (looking at these photos, the rearward one), and a second orbiter was destroyed there when a hangar collapsed under snow on the roof.
More are in Moscow. The other three of the actual orbiters were at Tushino, but apparently are to an extent broken up, along with the simulator. Elsewhere in Moscow there's one at Zhukovsky, and the one in Gorky Park. Nearest to western Europe is one at the engine factory in Kaliningrad, it was the pioneer used for piggyback flying.
Very interesting set of photographs. Thank you for the link.
