Jiayu Pass

Jiayu Pass or  Jiayuguan  (simplified Chinese: 嘉峪关; traditional Chinese: 嘉峪關; pinyin: Jiāyù Guān; literally: "Excellent Valley Pass") is the first pass at the west end of the Great Wall of China, near the city of Jiayuguan in Gansu province. Along with Juyong Pass and Shanhai Pass, it is one of the main passes of the Great Wall.

The pass is located at the narrowest point of the western section of the Hexi Corridor, 6 kilometres (3.7 mi) southwest of the city of Jiayuguan in Gansu. The structure lies between two hills, one of which is called Jiayuguan Pass. It was built near an oasis that was then on the extreme western edge of China.

The pass is trapezoid-shaped with a perimeter of 733 metres (2,405 ft) and an area of more than 33,500 square metres (361,000 sq ft). The length of the city wall is 733 metres (2,405 ft) and the height is 11 metres (36 ft).

There are two gates: one on the east side of the pass and the other on the west side. On each gate there is a building. An inscription of "Jiayuguan" in Chinese is written on a tablet at the building at the west gate. 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.
