Casa Grande Ruins protects a large earthen Great House built about 700 years ago by Ancestral Sonoran Desert People who farmed with long irrigation canals. You view it up close from a short path, sheltered under a steel roof first built in 1932, and a small museum covers the people who built it. Come early in the day from late spring to fall, when the desert gets very hot.
