This volume is published in conjunction with an exhibition presenting the radical architects and architect groups who emerged in Florence in the late 1960s. It was a period characterized by crisis in the city, which extended to the wider political and social tension occurring throughout Italy. The related writings, drawings, and projects produced by these seven actors - Archizoom, Remo Buti, Gruppo 9999, Gianni Pettena, Superstudio, UFO, and Zziggurat - have influenced generations of architects, historians, designers, and artists around the world.
