Jiayuguan Pass
2 min readJiayuguan Pass is the first pass at the west end of the Great Wall of China and was built during the Ming Dynasty.It is located 6 kilometers southwest of Jiayuguan City which is in Gansu Province.It is located at the foot of Jiayuguan Hil，between two hills of which the Pass lies，so earned the name“The First and Greatest Pass under the Heaven”.This is different from“The First Pass under the Heaven”，which is located at the east end of the Great Wall near Qinhuangdao City in Hebei Province.
The Pass is located at the narrowest point of the western section of the Hexi Corridor，and Jiayuguan often has the meaning of“Nice Valley”.It was also a must point of the ancient Silk Road.
The pass is trapezoid-shaped with a perimeter of 733 meters and with an area of more than 33 500 square meters.The total length of the city wall is 733 meters and the height is 11 meters.There are two gates-with one lo-cated on each of the east and west sides of the pass.On each gate there is a building.On the building at the west gate，the Chinese inscription of “Jiayuguan Pass”is writen on a tablet.The south and north sides of the pass are connected to the Great Wall.There is a turret on each corner of the pass.On the north side inside the two gates，there are wide roads leading to the top of the pass.
The structure was initially built in 1372 during the Ming Dynasty and has a history of more than 600 years.A legend says that when Jiayuguan Pass was to be built，the official in charge of this project asked the designer to count how many bricks and other materials would be used precisely.The designer gave him a specific number.But when the proiect was finished，one brick was left which was placed on the pass as a symbol of commemo-ration.
Jiayuguan itself consists of three defense lines-an inner city，an outer city and a moat.
