Mesa Verde National Park is a U.S. National Park and UNESCO World Heritage Site located in Montezuma County, Colorado, United States. The park occupies 81.4 square miles (211 km2) (211 square kilometers) near the Four Corners and features numerous ruins of homes and villages built by the ancient Pueblo people known as the Anasazi. The Anasazi made this stone village their home in the 1200s AD. It is best known for several spectacular cliff dwellings — structures built within caves and under outcroppings in cliffs — including Cliff Palace, which is thought to be the largest cliff dwelling in North America. The Spanish term Mesa Verde translates into English as "green tableland".
