Few Constructivist projects made it through the World Wars, but if you're looking for those that did, you'd be wise to travel to Yekaterinburg, Russia. With over a dozen complexes, the city probably has the world's biggest collection of Constructivist buildings—and it's definitely the only place with a hotel in the shape of a hammer and sickle.
The fascinating video above by Ural Life and Culture tours the city and surveys the elements common to Constructivist buildings. Yekaterinburg was a laboratory for Constructivist architects who started building there soon after the movement was founded in Moscow in 1921. Architects from all over the Soviet Union, Poland, and Germany designed 4-5 story apartment blocks and office towers to replace single story wooden houses. The Soviets also introduced new typologies like public baths, kindergartens, and a 14-building secret police complex called the "Little Town of Cheka Officers," with covered passages so residents could walk between buildings indoors.
