Overhanging Great Wall 2DB140CD E0EC 437C B9F9 381D2FA5D760

The Overhanging Great Wall is an important part of the defense network of Jiayuguan (Jiayu Pass). It was built in the year 1539- 1540 during the Ming Dynasty (1368-1644) to strengthen the defensive capability of the Jiayuguan area.
Built on the eastern slope of Black Mountain, it is not visible to anyone looking from west to east. Enemies thought they could enter inner China from here, the Black Mountain Canyon, as long as they rounded the Jiayuguan Pass. However, they were totally mistaken. After they went over the mountain with great difficulty, they found a very firm barrier in their path that was impossible to cross.
