The top of a restored kiva, a ceremonial chamber, with an access ladder visible. Kivas varied from settlement to settlement but all were built of rock, covered with plaster and contained roof entries, a firepit, and a "sipapu", or spirit hole, through which the Indians believed their ancestors entered the world. - DesertUSA

Located at the Pecos National Historical Park. The name Pecos comes from the Spaniards. The original name was Cicuye Village, a quadrangular pueblo inhabited by more than 2000 people. The pueblo contained numerous ceremonial chambers, called "kivas", and was built around a central plaza on a rocky ridge.

A Coronado chronicler described Cicuye as "a strong village, four stories high. The houses do not have doors below, but instead ladders are used which can be lifted up like a drawbridge."
