The Maijishan Grottoes are a series of nearly 200 man-made caves cut in the side of the hill of Maijishan in northwest China during the 4th century, featuring thousands of sculpted statues and murals carved into its cliffs.
Constructed under the Qin dynasty in the Gansu province, over seven thousand Buddhist sculptures and a thousand square meters of murals were carved from the caves' red sandstone.
A series of platforms were built in the outside, providing visitors navigation in the vertical slopes of Maijishan as well as granting access to the caves inside.
They were also the home of the Chinese Assassins until 1524, when the Templars began a purge of their enemies. The grottoes were then converted into a secret Templar prison led by one of the Eight Tigers Gao Feng. However, in 1526, the Assassin Shao Jun managed to infiltrate Maijishan Grottoes by allowing herself to be captured as bait and killed Gao Feng. Jun also freed the Assassin informant Hong Liwei and retrieved the remaining Assassin scrolls in the grottoes.
