The Twin Towers are part of the Square Tower Group on the rim of Little Ruin Canyon. The Square Tower Group contains the largest collection of ancestral Puebloan structures at Hovenweep. The remains of nearly thirty kivas (Puebloan ceremonial structures) have been discovered on the slopes of Little Ruin Canyon, and a variety of other structures are perched on the canyon rims, balanced on boulders and tucked under ledges. It's possible that as many as 500 people occupied the Square Tower area between A.D. 1200 and 1300.
