Jianmen Pass is located in Jiange County, Guangyuan City of Sichuan Province.

The gate of the pass was built on the middle part of the Dajian Mountain as a strategic position.

The construction of the gate was related to the Three Kingdoms era strategist, Shu Han chancellor Zhuge Liang.

While Zhuge Liang repaired the gallery roads, he found the terrain in Jiange was a naturally perfect place to set up a defensive position for Shu; therefore, he ordered a military gate to be built on the pass.

In 1932, because the local government was building a road across the Jianmen Pass, they demolished the structure which was built in the Ming Dynasty.
