This group of buildings was crafted into a cliff face over 1,000 years ago. Visitors must climb over the cliff and through narrow tunnels, security features created by the builders. The sturdy, 32 foot, entrance ladder is made from pine trunks. My photograph of Balcony House features two kivas (circular ceremonial chambers) built into the plaza. I am standing in the plaza. There are 40 rooms in Balcony House.
