In his book Cosmic Communist Constructions Photographed, French photographer Frédéric Chaubin captures the eerie beauty of Soviet brutalism. In his quest to document Brezhnev-era architecture, he stumbled upon 90 Soviet buildings scattered across 14 former-USSR republics. The diversity and lack of a recurring theme across the buildings signaled the end of the Soviet Union.
