Acoma Pueblo (Sky City)
The Pueblo, believed to have been established in the 12th century or even earlier, was chosen in part because of its defensive position against raiders. It is regarded as the oldest continuously inhabited community in the United States. Access to the pueblo is difficult as the faces of the mesa are sheer. Before modern times access was gained only by means of a hand-cut staircase carved into the sandstone.

There are several interpretations of origin of the name "Acoma". Some believe that the name Acoma comes from the Keresan words for the People of the White Rock, with aa'ku meaning white rock, and meh meaning people. Others believe that the word aa'ku actually comes from the word haaku meaning to prepare; a description that would accurately reflect the defensive position of the mesa's inhabitants.

Today, fewer than 50 tribal members live year-round in the earthen homes of Sky City. Those living in the community tend the massive San Estévan del Rey Mission, completed in 1640. Both the mission and pueblo have been designated as a Registered National Historical Landmarks. Nearly 3,000 additional tribal members live in the nearby villages of Acomita, McCarty’s and Anzac.
