1 Best Sight in Phoenix, Scottsdale, and Tempe, Arizona

The evolving complex and community of Arcosanti was masterminded by Italian architect Paolo Soleri to be a self-sustaining habitat in which architecture and ecology function in symbiosis. Building began in 1970, but Arcosanti hasn't quite achieved Soleri's original vision. It's still worth a stop to take a tour, have a bite at the café, and purchase one of the hand-cast bronze wind bells made on-site.
