This publication surveys the work of Italian critic, architect, and visual artist Gianni Pettena. Focusing on a rich ten-year period of production that began in the mid-sixties, it brings new attention to the artistic and intellectual practice of a figure known primarily as one of the main exponents of the Radical Architecture movement. International curators and writers consider a span of projects about landscape and the built form as well as objects and works documenting Pettena's interests in labor, temporality, action, and the event. Published on the occasion of the exhibition "About Non-Conscious Architecture" at Galleria Giovanni Bonelli, Milan, 2017, the book also contains a republished conversation between Pettena and artist Robert Smithson and an illustrated index detailing the trajectory of Pettena's body of work and research. Copublished with Galleria Giovanni Bonelli Contributors Pierre Bal-Blanc, Adam Budak, Luca Cerizza, Émile Ouroumov, Marco Scotini, Elisabetta Trincherini
