Details of moat

A moat, also called a city wall, is defined as a river that people dig around the city wall. In ancient times, it was used for defense. It was excavated in ancient times and surrounded the whole city, palaces, temples and other major buildings. It has a defensive function and can prevent the invasion of enemies or animals.

This kind of moat, which is dominated by nature and supplemented by man-made, is more in China and the world. The most typical cities are Nanjing, Xi 'an, Jingzhou, Xiangyang, Chongqing, Hengyang, Changde, Ganzhou, Jishui Town and Hotan Town.

Many countries in the world have dug moats in ancient times, such as the Forbidden City in China, the Ming City Wall in Xi 'an, the Ming City Wall in Nanjing, the ancient city wall in Jingzhou, the moat around Jinan (the park around Jinan), the moat in Xiangyang, the ancient city of Hsinchu in Taiwan Province, the old city of Zuo Ying, Huang Jincheng in Yizai, Matsumoto City in Japan, the Imperial Palace in Edo (now Tokyo) and other ancient cities, and even castles and palaces in European countries. Many castles in Europe have wooden bridges, which can be raised on the moat to facilitate access and prevent the enemy from entering.
