The volume celebrates the birth of the metropolis Berlin: The realized buildings of the expressionist utopia captivate with their unwavering commitment to form and a skillful handling of material, color, and light. Unlike contemporary Bauhaus architecture, the architectural and urban understanding is characterized by complexity, verticality, and theatricality - the modern metropolis has been created. Fragments of Metropolis documents 120 buildings in Berlin and its surroundings through contemporary photographs and drawings. A detailed index and clear maps complete this reference work.
