Delving into the fourth age of Soviet architecture from 1970 to 1990, Fr√ ©d√ ©ric Chaubin explores 90 buildings in 14 former Soviet Republics. This period, considered by the author as an unknown burgeoning, contrasts with earlier architectural trends, showcasing a chaotic impulse driven by a decaying system.

The book covers a spectrum, from a summer camp inspired by lunar base sketches (Prometheus youth camp, Bogatyr) to the "speaking architecture" of the USSR's final years, featuring a crematorium with concrete flames (Crematorium, Kiev) and a technological institute with a crashed flying saucer on the roof (Institute of Scientific Research, Kiev). These extraordinary structures, with their puzzle of styles and outlandish strategies, serve as remnants of a collapsing system.
