In 1987, Berlin as a whole became a laboratory for architecture. A wide range of notable buildings with a unique density was created in the East and the West in connection with the city's 750th anniversary. While the buildings were vilified at the time, they now appear as important witnesses to a "postmodern" era of building, which called the traditional architecture of the modern living environment into question. Today, the buildings have disappeared, been modified, or are threatened with demolition. For the first time, the exhibition and publication examine the significance of the architectural visions developed in East and West Berlin in the final decade before the fall of the Berlin Wall.
