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.
The city is particularly remarkable when you consider Russia's track record with its Constructivist architecture. The country's most famous Constructivist building, Konstantin Melnikov's house in Moscow, was only listed as a heritage site, after years of preservationist efforts, in 2013.
