As one of China's three major grottoes, the Yungang Grottoes are located at the southern foot of Wuzhou Mountain, 16 kilometers west of Datong City, Shanxi Province, on the north bank of Shili River. Formerly known as the Wuzhou Mountain Grand Caves Temple, the grottoes were carved during the era when the Northern Wei Dynasty established its capital in Pingcheng (today's Datong, Shanxi). With a history of 1600 years, the grottoes stretch east to west for one kilometer, housing 254 grottoes and niches, including 45 major caves with over 59,000 statues, making them a pinnacle of Chinese Buddhist art and representing the highest level of world sculpture in the 5th century.
