The Longmen Grottoes, located near Luoyang, Henan Province, are a treasure house of ancient Buddhist cave art. The grottos were hewed and carved during the Northern Wei Dynasty (386-534), when the rulers relocated their capital at Luoyang near the end of the 5th century. At that time Buddhism was spreading east into China and was venerated by the imperial court. The Buddhists adopted the practice of carving rock temples, dedicated to the Buddha. (Source: China.org.cn)
