Laolongtou

From Wiki China org cn

Four kilometers south of Shanhaiguan, Laolongtou (Old Dragon's Head) is the easternmost end of the Great Wall, which stretches 23 meters into the sea like a dragon drinking water, hence its name. This part of the Great Wall was built in the 7 th year of Wanli reign in the Ming dynasty (1579) and was mended in the 7 th year of Kangxi reign in the Qing dynasty (1668). Emperors Kangxi and Qianlong of the Qing Dynasty would stop here for a visit on their way to Fengtian (Present - day Shenyang) to worship their ancestors, which makes the city even more worthy of its name.

It consists of the Estuary Stone City, Jinglu Watchtower, Wangshou Watchtower, Nanhaikou Pass, Chenghai Tower, Ninghai City and Binhai City.
