The cultural heritage authority in Beijing on Wednesday showcased its latest architectural founding — a section of a city wall from the Jin Dynasty (1115 -1234). Beijing, previously called Zhongdu, was the capital of the Jin kingdom, built by Jurchens. This period marked the first time that Beijing was known as the capital of a Chinese kingdom. At the excavation site located in Beijing's southwestern Fengtai district, a 60-meter section of city wall, a 66-meter-wide moat, and some bricks and china chips have all been found. The site will be developed into a park for tourists in the future, officials said.
