National Monument - Utah, Colorado, United States
Hovenweep National Monument protects six groups of Ancestral Puebloan villages spread along 20 miles of mesa tops and canyons. The monument is famous for its distinctive square, oval, circular and D-shaped towers built between A.D. 1200 and 1300. These well-preserved structures demonstrate the sophisticated engineering and astronomical knowledge of their builders. The monument is managed by the National Park Service.
