Mogao Caves in 1900
During late nineteenth century and early twentieth century, Western explorers began to show interest in the ancient Silk Road and the lost cities of Central Asia, and those who passed through Dunhuang noted the murals and artifacts such as the Stele of Sulaiman at Mogao. The biggest discovery however came from a Chinese Taoist named Wang Yuanlu who appointed himself guardian of some of these temples around the turn of the century.
Some of the caves had by then been blocked by sand, and Wang set about clearing away the sand and made an attempt at repairing the site. In one such cave, on 25 June 1900, Wang discovered a walled up area behind one side of a corridor leading to a main cave.
