Located on the banks of the Moscow River, the Udarnik was once a legendary movie theater built for the Soviet party members who lived in the nearby House on the Embankment apartment building. The space was turned into a casino in the 1990s, and then was idle for the better part of the 2000s. Its current incarnation began in 2012 through a partnership with the magazine Art Khronika; it's now used for showing avant-garde exhibits as well as for hosting prestigious art contests and other events, such as the Kandinsky Prize. It's only open when exhibits are on view, so check the website ahead of time.
