Aztec Ruins National Monument preserves ancestral Puebloan structures built and used between 1100 and 1300 CE. Despite its name, the ruins have no connection to the Aztec civilization but were misnamed by early European-American settlers. The monument features a reconstructed Great Kiva, the only one of its kind, and well-preserved masonry buildings that demonstrate sophisticated ancient architecture. Managed by the National Park Service, the site provides insight into the complex society of the ancestral Puebloan people.
