This is Manege, a famous building in the very center of Moscow city. It was built in 1817 as a riding house close to Kremlin, and its construction was unique: 166m long and 45m wide building had no support (such as columns) inside. Very soon Manege turned to exhibition hall and remains in this role untill now.
In March of 2004 the building suffered the great fire, and what fire spared was later destroyed by 'reconstruction'. A 'new version' of Manege was open in 2005, though from an architectural point of view it has nothing in common with original building but appearance. Well, when big money is involved, there is no use to look for common-sense.
Anyway, Manege is still the main exposition hall in Moscow and, probably, in Russia.
