National monument, northern Arizona, U.S. Covering 360 acres (146 hectares), it comprises three historic cliff dwellings: Betatakin (Navajo: "Ledge House"), Keet Seel ("Broken Pottery"), and Inscription House, among the best-preserved and most elaborate cliff dwellings known.
The largest, Keet Seel, was first discovered by whites in 1895; the three sites were made a national monument in 1909. The dwellings were the principal home of the Kayenta Anasazi с 1250–1300. The 135 rooms of Betatakin are tucked into a cliffside alcove 452 ft (138 m) high and 370 ft (113 m) wide. Also situated in a cliff alcove are the 160 rooms and 6 kivas (ceremonial houses) of Keet Seel. Inscription House (closed to the public) has 74 rooms.
