Casa Grande Ruins National Monument
Casa Grande Ruins
A four-storey adobe Great House built by the Hohokam about 700 years ago, and America's first federally protected prehistoric site.
The Great House was built by ramming layers of caliche clay, and it rises about four storeys. Openings in its walls may have been used to observe the positions of the sun and moon. It is now protected by a large steel roof added in 1932. In 1892 it became the first prehistoric site in the United States to receive federal protection. The visitor centre has a small exhibition hall. A visit takes about 1 hour and is free. The site is in the town of Coolidge, about 1 hour southeast of Phoenix, and can be visited on the way to Tucson.
