The Longmen Grottoes (; lit. Dragon's Gate Grottoes) or Longmen Caves are one of the finest examples of Chinese Buddhist art. Housing tens of thousands of statues of Buddha and his disciples, they are located south of present-day Luòyáng in Hénán province, China. The images, many once painted, were carved as outside rock reliefs and inside artificial caves excavated from the limestone cliffs of the Xiangshan and Longmenshan mountains, running east and west. The Yi River  flows northward between them and the area used to be called Yique (伊阙, "The Gate of the Yi River"). The alternative name of "Dragon's Gate Grottoes" derives from the resemblance of the two hills that check the flow of the Yi River to the typical "Chinese gate towers" that once marked the entrance to Luoyang from the south.
