Shanhai Guan

Shanhaiguan is a historic city located in northeastern China, near the coast of the Bohai Sea. Shanhaiguan was first established as a military outpost during the Tang Dynasty (618-907 AD) to guard against foreign invaders from the northeast. Shanhaiguan played a significant role in Chinese history during the Qing Dynasty (1644-1912 AD), when it was the site of several major battles between the Qing Dynasty and the Eight-Nation Alliance during the Boxer Rebellion in 1900.

Shanhai Pass, also known as Shanhaiguan, is a significant pass on China's Great Wall.

It is situated on the east bank of the Shi River, between the Yan Mountains and the Liaodong Bay shoreline, in Shanhaiguan District, Qinhuangdao, Hebei province.
