Located on both sides of the Yishui River in the southern suburbs of Luoyang City, Henan Province, China, it is one of the four major grottoes in China and a world-renowned treasure trove of Buddhist art. Excavated from the Northern Wei Dynasty to the Tang Dynasty, it lasted for more than 400 years and showcased the peak of ancient Chinese Buddhist sculpture art. Known for its grand scale, exquisite art, and rich content. There are over 2100 caves, more than 100000 Buddha statues, as well as a large number of inscriptions and pagodas in the grotto complex. The most famous among them is the Lushena Buddha, which is 17.14 meters high and has a solemn and dignified face. It is an iconic sculpture of the Longmen Grottoes. In 2011, it was listed as a World Cultural Heritage site by UNESCO.
