From 1957 to 1972, the artistic and political movement known as the Situationist International (SI) worked aggressively to subvert the conservative ideology of the Western world. The movement's broadside attack on "establishment" institutions and values left its mark upon the libertarian left, the counterculture, the revolutionary events of 1968, and more recent phenomena from punk to postmodernism. In this book Simon Sadler investigates the artistic, architectural, and cultural theories that were once the foundations of Situationist thought, particularly as they applied to the form of the modern city. Simon Sadler searches for the Situationist City among the detritus of tracts, manifestoes, and works of art that the SI left behind. The book is divided into three parts. The first, "The Naked City," outlines the Situationist critique of the urban environment as it then existed. The second, "Formulary for a New Urbanism," examines Situationist principles for the city and for city living. The third, "A New Babylon," describes actual designs proposed for the Situationist City.
