Jiayuguan Fort is in the seven km southwest of Jiayuguan city and is the end point in the west of Great Wall. It was built in Ming Dynasty and important for military.

Jiayuguan Fort is facing Qilian Mountain in south and Mazongshan Mountain in north, only 15 km between the two mountains. It is regarded as the “gullet” of Hexi Corridor. Hence Jiayuguan Fort is the first pass in the west of Yellow River.

Jiayuguan includes three parts, inside city, outside city and moat. Such a structure was for the military recovery at old time. Meanwhile, it may echo each other with Shanhaiguan in Hebei province, being the top pass in China.
