Introduction to the 10,000-meter Great Wall of Nanjing: The Great Wall of Nanjing was built in the early 1990s, using the world-renowned Badaling Great Wall as a blueprint and replicating it to a 1:1 scale. The Great Wall is a 3,000-meter-long wall with a platform height of 9 meters and a surface width of 4.3 meters. There are also three castles, Dafengguan, Wangyue Platform and Wangjiang Tower, as well as 824 stone steps. The color, specifications and slope ratio of the long stones used in the city wall are exactly the same as those of the Great Wall in Beijing. In terms of appearance, momentum and style, it reproduces the style of the Badaling Great Wall.
