Published on the occasion of the exhibition "Soviet Modernism 1955–1991. Unknown Stories" (07.11.2012–25.02.2013) at the Architekturzentrum Wien, this book offers a unique account of hitherto largely disregarded modernist Soviet architecture. Based on a ground-breaking research project, this book presents a history of architecture in the fourteen non-Russian Soviet republics, illustrated with a wealth of previously unpublished photographs and plans.
