The phrase the "New Frankfurt" is used to refer to one of the most important and ambitious urban renewal projects of Classical Modernism, implemented in Frankfurt am Main between 1925 and 1932. Planned by the municipal authorities and coordinated by architects Ernst May and Martin Elsässer, it comprised not only residential buildings and housing estates but also schools, hospitals, and administrative and sacred buildings, including architectural icons such as the Grossmarkthalle (now the seat of the European Central Bank). This publication presents the most important buildings of the "New Frankfurt", describes their socio-political background, introduces the protagonists, and explains their work in the context of modernism. The author, a renowned expert on "Neues Bauen", presents the subject in a scholarly and at the same time lively way. The book is not only an ideal travel companion, therefore, but is also suitable as an easily accessible introduction to a complex and exciting subject.
