Located in the heart of Berlin, Alexanderplatz is associated with the famous novel by Alfred D?blin, with the avant-garde designs of Mies van der Rohe, and with the office buildings of Peter Behrens. In the former GDR, it was the capital's major square. Today it assumes a key position in the future development of Berlin. The future form of Alexanderplatz was determined in an ideas competition. Hans Kollhoff, the competition winner, designed, through a significant ensemble of high-risers, a new city district which sets new standards for Berlin. The second prize was awarded to Daniel Libeskind who presented his avant-garde concept of the square with consummate ease. An introductory text covers the history of Alexanderplatz, while the rest of the book documents the competition proceedings which stimulated heated debates on the future of Berlin.
