嘉峪关是古“丝绸之路”的交通要冲，又是明代万里长城的西端起点。在这里，两千多年前开辟的中国与西方经济文化交流的的“丝绸古道”及历代兵家征战的“古战场”烽燧依稀可见。这里是中国丝路文化和长城文化的交汇点，素有“河西重镇”、边陲锁钥“之称。

The pass is trapezoid-shaped with a perimeter of 733 meters and 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: 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.

Jiayuguan consists of three defense lines: an inner city, an outer city and a moat.
