Using the hashtag #SOSBritalism, the Deutsches Architekturmuseum (DAM, German Museum of Architecture) in Frankfurt on the Main and the Wustenrot Foundation participate in this campaign, and have developed a vast collaborative research project. The result of this research to date is a global survey of brutalist architecture of the 1950s, 1960s and 1970s, presented in an exhibition at DAM in autumn 2017 and a coinciding and uniquely comprehensive book. Some 100 contributors document around 120 key buildings from this period, including many previously unpublished discoveries that are in acute danger of loss through neglect or intended demolition. Moreover, the book features overviews of brutalism in architecture in twelve regions around the world. Case studies of hotspots such as the Macedonian capital Skopje or New Haven, Connecticut, and essays on the history and theory of brutalism round out this lavishly illustrated book. The supplement collects papers of an international symposium on brutalism in architecture held in Berlin in 2012.
