Yungang Grottoes is ancient Chinese Buddhist temple grottoes near the city of Datong in the province of Shanxi, the last city before I reached my destination, Beijing. They are excellent examples of rock-cut architecture and one of the three most famous ancient Buddhist sculptural sites of China. The others are Longmen and Mogao grottoes.
Yungang Grottoes were made a UNESCO World Heritage Site in 2001. The Yungang Grottoes is considered by UNESCO a "masterpiece of early Chinese Buddhist cave art... [and] ...represent the successful fusion of Buddhist religious symbolic art from south and central Asia with Chinese cultural traditions, starting in the 5th century CE under Imperial auspices."
