In 1969, the Archizoom group, while carrying out an experimental work in the field of design, also undertook a research project on environment, mass culture and the city, which led to the project No-Stop City'. For the very first time, the whole of this founding project of 1970s radical architecture is presented together in this publication. Designed by Andrea Branzi, this unique document provides a political reflection on ideas about urbanism and architecture that has influenced a whole generation of architects.
