The Maijishan Grottoes, formerly romanized as Maichishan, are a series of 194 caves cut in the side of the hill of Majishan in Tianshui, Gansu Province, northwest China.
This example of rock cut architecture contains over 7,200 Buddhist sculptures and over 1,000 square meters of murals. Construction began in the Later Qin era.
They were first properly explored in 1952–53 by a team of Chinese archeologists from Beijing, who devised the numbering system still in use today. Caves #1–50 are on the western cliff face; caves #51–191 on the eastern cliff face. They were later photographed by Michael Sullivan and Dominique Darbois, who subsequently published the primary English-language work on the caves noted in the footnotes below.
