Ideological dreams Photographer Frédéric Chaubin reveals 90 buildings sited in fourteen former Soviet Republics which express what he considers to be the fourth age of Soviet architecture. His poetic pictures reveal an unexpected rebirth of imagination, an unknown burgeoning that took place from 1970 until 1990. Contrary to the 1920s and 1950s, no “school” or main trend emerges here. These buildings represent a chaotic impulse brought about by a decaying system. Their diversity announced the end of the Soviet Union.
