How many Xuanwumen are there in China?

Xuanwu Gate is an ancient city gate in the ancient city of Nanjing. It is now the gate of Xuanwu Lake Park.

The largest existing ancient city is Nanjing City. It was built when Zhu Yuanzhang, the emperor of the Ming Dynasty, made Nanjing his capital and took 21 years to complete. The city of Nanjing in the Ming Dynasty had a circumference of 33.65 kilometers, an average city height of 12 meters, and a width of 10 to 18 meters. The city wall is built with stone foundations and huge bricks. The city bricks are made of high-quality clay and white porcelain clay, and each piece weighs 20 to 40 kilograms. The bricks are also printed with the name of the county where the bricks were made, the name of the person who fired the bricks, and the date of firing. Glutinous rice slurry mixed with lime is used as a binder, which is very strong. Although it has been exposed to wind and rain over the years, there are still 20 kilometers of city walls that have been preserved intact. Nanjing has a total of 13 gates, 13,600 crenellations, and more than 200 fortresses. The largest one is the Jubao Gate due south
