Laolongtou is located 5 kilometers south of Shanhaiguan District, Qinhuangdao City. It is the eastern part of the Great Wall in Ming Dynasty and the only land and sea military defense system of the Great Wall in Wan Li, which integrates mountains, seas, customs and cities. In the 600-year-old changes, the old leaders have written a vicissitudes of history, which provides a good teaching material for patriotism. Laolongtou is 4 kilometers away from Shanhaiguan. In the Ming Dynasty, the Great Wall spanned mountains and sent a dragon into the Bohai Sea, so it was called the "old dragon head".

The old faucet consists of Shicheng, Jinglutai, Nanhai Kouguan and Chenghailou. The old dragon head is high and steep, which was built by Qi Jiguang, the commander of Jizhen Town in Ming Dynasty. The Old Dragon Head is not only a very skillful military facility extending into the sea, but also the only excellent place in the Great Wall of Wan Li related to many landscapes such as mountains, seas and colors.

Architectural characteristics of the old dragon head

The foundation of this stone city on the sea is very solid and will not be destroyed after hundreds of years of seawater erosion. It is said that when it was first established, many iron pots were locked at the bottom of the sea to reduce the influence of seawater on Shicheng. This unique construction method has been recorded in the history of architecture.

During the more than 200 years from the Hongwu period in the early Ming Dynasty to the end of the Ming Dynasty, the old faucet was continuously built and gradually improved. Until the Qing Dynasty, when the Great Wall was unified inside and outside, the old dragon head lost its military defense function and became an excellent place for emperors, generals and literati to watch the sea. In particular, the Qing emperor, who claimed to be the incarnation of the "dragon", gave supreme significance to guarding the sea to which the "dragon" attached. Emperor Kangxi and Emperor Qianlong have been to Laolongtou many times, leaving many poems and songs about Mo Bao.

The most famous building of the old faucet is Chenghai Tower, which is called the Great Wall connecting the sea and the sky. People fly to the top of hundreds of feet. Chenghai Tower is14.5m high,15.68m wide and12m deep. The building is divided into two floors, with brick and wood structure and sloping mountain double-eaves tile roof. There are also many stone tablets inlaid on the walls on both sides of Chenghai Building, which are engraved with poems recited by several emperors and many literati when they boarded the building.
