Qinhuangdao Bay

The coast around Qinhuangdao faces the western side of Liaodong Bay, where the mountains approach the sea. At Shanhaiguan the narrow passage between mountain and water was fortified under the Ming. South of the pass, the wall reaches the shore at Laolongtou, where a stone fort projects into the waves. The coastal works protected the approach to the pass, linking the inland defences with the sea and making this bay a frontier as well as a maritime route.
