Beijing: Multiple discoveries, including remnants of a city gate from the Jin Dynasty (1115-1234) capital of Zhongdu in Beijing, were unveiled by the Beijing Archaeological Research Institute at a press conference. Remnants of the city gate, excavated for the first time, provide a valuable reference for understanding the ancient city's layout. According to Qatar News Agency, the recent excavation efforts unearthed remnants of Duanli Gate, the southwest gate of the outer city of Jin's capital. It is noted as a rare well-preserved large-scale architectural structure, as mentioned by Ding Lina, a researcher with the institute. Zhongdu served as Jin's capital for more than six decades during the dynasty's peak and was later abandoned around the end of the Yuan Dynasty (1271-1368). The director of the institute, Guo Jingning, stated that previously, knowledge of Zhongdu was primarily based on documents and scattered archaeological findings. The absence of landmarks such as gates and roads had left the understand ing incomplete. In addition to the city gate, archaeologists have also unearthed a wealth of related remnants of the outer city of Zhongdu, including city walls, moats, and drainage ditches, as well as pottery, porcelain items, bricks, and tiles.
