Book excerpt: "This book examines the unique socialist-modernist architecture built in the 20th century in Central and Eastern Europe, as a source of heritage and of existing and potential value for present and future generations. Due to the historical context in which it was created, such architecture remains ambiguous. On the one hand, the wider public associates it with the legacy of the unpleasant period of the real socialist economic regime. Yet, on the other hand, it is also a manifestation of social modernization and promotion of a significant proportion of the population. The book focuses particularly on concrete heritage, a legacy of modernist architecture in Central and Eastern Europe, and it was this material that enabled their rebuilding after World War II and modernization during the following decades. The authors search for the value of modernist architecture and using case studies from Poland, Bulgaria, Northern Macedonia, Lithuania and Slovenia, verify to what extent this heritage is embedded in the local socio-economic milieu and becomes a basis for creating new values. They argue that the challenge is to change the ways we think about heritage, from looking at it from the point of view of a single monument, to thinking in terms of a place with its own character and identity that builds its relation to history and its embeddedness in the local space. Furthermore, they propose that preservation of existing concrete structures and adapting them to modern needs is of great importance for sustainability. With increasing awareness of the issue of preserving post-war architectural heritage and the strategies of dissonant heritage management, this multidisciplinary study will be of interest to architecture historians, conservators, heritage economists, urban planners and architects"--
