In this volume photographer Frédéric Chaubin reveals 90 buildings sited in fourteen former Soviet Republics which express what could be considered as the fourth age of Soviet architecture. They reveal an unexpected rebirth of imagination, an unknown burgeoning that took place from 1970 until 1990. Contrary to the twenties and thirties, no “school” or main trend emerges here. These buildings represent a chaotic impulse brought about by a decaying system. Their diversity announces the end of Soviet Union.
