Montezuma Castle National Monument preserves one of the best-preserved cliff dwellings in North America, built by the Sinagua people in the 12th century. The five-story, 20-room limestone alcove dwelling sits 90 feet above the valley floor and demonstrates remarkable ancient engineering. The monument also protects Montezuma Well, a natural limestone sinkhole that has provided water for over 1,000 years. It is managed by the National Park Service.
