Catalog of the exhibition "Radically Modern. Planning and Construction in 1960s Berlin" at the Berlinische Galerie, Berlin from 29th May to 26th October 2015. Destroyed in the Second World War and divided by the Wall, Berlin experienced a veritable construction boom during the 1960s. Inspired by the spirit of a new beginning and technological euphoria, urban planners and architects designed radical new cityscapes for a modern society. Often unjustly criticized as inhumane or unsightly, important examples from this period of architecture have often already been torn down, disfigured by later alterations, or are threatened with demolition today. This publication for the first time takes a look at the context of this architecture's emergence, examining formal aspects and underlying international influences on the architecture developed in both East and West Berlin.
