南京城墙与中华门

The Nanjing Ming City Wall conforms to the boundaries of mountains, rivers and palaces. It is not a regular rectangle. It is a brick defense system with outstanding preservation scale. The Zhonghua Gate contains multiple barbican and hidden soldier spaces, while other open sections present different relationships with lakes and communities. The city wall is not a continuous open trail along its entire length, so it is more reasonable to choose a section for an in-depth experience.
