Its original dwellers would have climbed the rock face using narrow toeholds; its limited accessibility made it easy to defend against intruders. Cliff Palace was constructed in the cliff face with sandstone blocks, mortar, and wooden beams. It once had over 150 rooms and 25 kivas and was probably used for ceremonial purposes. As with Balcony House, Cliff Palace is only accessible on a ranger-guided tour.
Cliff Palace and Balcony House are ancient cliff dwellings that the ancestral Pueblo Indians inhabited in the 12th and 13th centuries. Located in Mesa Verde National Park, both are World Heritage Sites and National Monuments. Balcony House had forty-five rooms and two kivas (ovens), and it can only be accessed on ranger-guided tours. Tour participants must climb a thirty-two foot ladder and then crawl through a twelve-foot tunnel to access Balcony House.
