Luoyang (洛陽) is a city in Henan province, China.
It lies on the southern bank of the Yellow River. It has been a national capital of China.
In AD 493 the Northern Wei Dynasty moved its capital from Datong to Luoyang and started the construction of the artificial Longmen Caves. More than 30,000 Buddhist images from the time of this dynasty have been found in the caves.
The Longmen Grottoes were listed by the UNESCO among the World Heritage Sites in 2000.
