The caves homes of Guyaju (Guyaju meaning, ancient cliff
dwelling) are about 90km northwest of Beijing, China. They were
occupied during China's Tang Dynasty (AD 618-907) by the Xiyi
people. There are over 100 homes carved in to the hillside. The
homes, some with stylish pillars of stone, are arranged in two
village clusters supplied with fresh water from a natural
spring. When they were occupied the homes would have had a
timber frame façade with thatch roofs.
