The Maijishan Grottoes are a series of caves cut into the mountain of Maijishan. They are located in the Gansu Province in northwest China.
They were constructed under the Qin dynasty in the 3rd and 4th centuries. Its name means "wheatstack mountain" and is made of red sandstone.
The impressive appearance of the mountain is just the surface of the wonder, since the grottoes contain over seven thousand Buddhist sculptures and over a thousand square meters of murals, in more than two hundred caves.
From the outside, a series of platforms can be seen, allowing people to navigate the vertical faces of the mountain as well as granting access to the caves which go deep inside.
