Juyongguan Pass is located in an 18 kilometer-long valley named 'Guangou' which is inside Changping County more than 50 kilometers from Beijing City. It is one of the three greatest passes of Great Wall of China. The other two passes are jiayuguan and shanhaiguan. This Pass was connected to the Great Wall in the Northern and Southern Dynasties.
The present Pass was initially built in the Ming Dynasty and received much renovation later. It is a very important strategic place connecting the inner land and the area near the northern border of China. It is also a defensive place for the ancient Beijing City. So it is wanted by all the military parties.
As there are lush flowers and trees around the Pass like layers of green waves, so it got the good name of 'Juyong Green Layers', which belongs to one of 'Yanjing Eight Best Sceneries'.
