18 of the Most Unique, Strange, Unusual Houses Ever Built

3.The Ancient Cliff House, Guyaju, China

Over 110 rooms were carved into the side of a cliff about 92km northwest of Beijing in the Tang Dynasty. The Xiyi people lived in them and built the communal caves near a natural spring.

The Guyaju Caves are known as the largest cliff residence ever discovered in China and are also known as “the biggest maze of China”. Stone steps and ladders were used to connect the different levels, and inside were found stone hearths, wardrobes, beds and mangers. At the highest level of the communal cave was found a two storey stone house, featuring furniture which may have belonged to the leader of the tribe.
