Arcosanti, a city of sci-fi proportions designed by Frank Lloyd Wright disciple Paolo Soleri, rises from a tract of secluded Arizona desert that is marked only by cacti and dusty dirt roads. It is one of the last-standing utopian eco-communities born of the 1970s and, more directly, of Soleri’s theory of “arcology,” the seamless confluence of architecture and ecology. Described by Soleri as an “urban laboratory,” the idiosyncratic stone buildings that make up the small city’s core (and which are still being erected, as funds allow) house all manner of creative activities—amphitheaters for performances, foundries and ceramics studios for artmaking. In Arcosanti’s early days, recruitment posters lured residents with a potent statement: “If you are truly concerned about the problems of pollution, waste, energy depletion, land, water, air and biological conservation, poverty, segregation, intolerance, population containment, fear and disillusionment. Join us.” Today, three years after Soleri’s death, the small community of some 50 residents that remain at Arcosanti still live according to this mantra, with the goal of finally realizing the architect’s vision for an idyllic eco-city.
