Juyongguan or Juyong Pass (simplified Chinese: 居庸关; traditional Chinese: 居庸關; pinyin: Jūyōng Guān) is a mountain pass located in the Changping District of Beijing Municipality, over 50 kilometers (31 mi) from central Beijing. The Great Wall of China passes through, and the Cloud Platform gate was built here in 1342 CE.
The pass had many different names during former Chinese dynasties. However, the name “Juyongguan” was used by more than three dynasties. It was first used in the Qin Dynasty when Emperor Qinshihuang ordered the building of the Great Wall. Juyongguan pass was connected to the Great Wall in the Southern and Northern Dynasties era.
The present pass route was built in the Ming Dynasty and received much renovation later. It was a very important strategic place connecting the inner land and the area near the northern border of China. It was also used to defend the ancient city of Beijing.
In the middle of the Juyongguan (pass) and Guangou Valley, there is the Cloud Platform gate, also known as the “Crossing Street Tower”. It was built in 1342 during the Yuan Dynasty, and made of white marble with a height of 9.5 metres (31 ft). There were originally three white pagodas atop the platform, giving it the name of “Crossing Street Tower”. They were each destroyed in the transitional period between the late Yuan and early Ming Dynasties. In the early Ming Dynasty, a Buddhist Tai’an Temple hall was built on the platform. It was destroyed in 1702 during the Qing Dynasty.
