Arcosanti is an experimental town that began construction in 1970 in central Arizona, 70 mi (110 km) north of Phoenix, at an elevation of 3,732 feet (1,130 meters). Architect Paolo Soleri, using a concept he calls arcology (a portmanteau of architecture and ecology), started the town to demonstrate how urban conditions could be improved while minimizing the destructive impact on the earth.
The Arcosanti site contains a camp area that was built for the original construction crew. It is used today as additional housing and is home to the agricultural department which maintains greenhouses, gardens, and agricultural fields. Additional terraced greenhouses are planned along the slope of the main building site to provide gardening space and collect heat which will be funneled throughout the buildings.
At present, the town is primarily an education center, with students from around the world visiting to attend workshops, classes, and continue construction. It is also a tourist attraction with 40,000 visitors a year. Tourists can take a guided tour of the site or make reservations to stay overnight in guest accommodations.
Some of the funding for Arcosanti comes from the sale of metal and ceramic bells that are made and cast from bronze on site. Additional funding comes from donations and fees for workshops which run up to five weeks long. Much of the present construction at Arcosanti is done by workshop participants and volunteers.
