Aztec Ruins National Monument features a preserved 12th-century ancestral Puebloan great house. The site includes the only fully reconstructed Great Kiva in North America, built in the 1920s atop original 900-year-old foundations. The masonry architecture showcases T-shaped doorways and original wooden roof beams dating to the 1100s. It is a UNESCO World Heritage Site as part of the Chaco Culture National Historical Park complex. The complex encompasses a series of multi-story buildings, plazas, and smaller residential structures. Visitors walk through a self-guided trail that leads directly through the restored great house rooms.
