The grottoes and niches of Longmen contain the largest and most  impressive collection of Chinese art of the late Northern Wei and Tang  Dynasties. These works, entirely devoted to the Buddhist  religion, represent the high point of Chinese stone carving.
Grottoes are one of the three most famous ancient sculptural sites in  China. There are over 2100 niches, more than 100,000 statues, some 40  pagodas and 3600 tablets and steles in the caves of Guyang, Binyang and  Lianhua. 
The area was inscribed on the UNESCO World Heritage List in November 2000.
