Paolo Soleri was an Italian-American architect and visionary whose experimental practice bridged sculpture, urban planning, and ecological design. Working from his Arizona studios, he developed innovative approaches to cast concrete forms and designed theoretical megastructures that integrated human habitation with natural systems. His utopian architectural philosophy emerged from apprenticeships in the American Southwest and a conviction that cities could be radically reimagined as three-dimensional, high-density organisms. Soleri's drawings, models, and built prototypes including Arcosanti remain singular documents of postwar architectural idealism.
