Simon Sadler searches for the Situationist City among the detritus of tracts, manifestos, 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 a Situationist City.
