Ruins of the Ancient City Wall of Nandun

　　The site is located in Dongfeng Administrative Village, Nandun Town, about 5 kilometers east of the city center. The Nandun ancient city wall is a relic of a Shang Dynasty city. Nandun was, in ancient times, the state of Dunzi, with city walls enclosing an area about two kilometers square. After more than 2,000 years of vicissitudes, the original southern, eastern, and western walls have all been flattened, leaving only a section of earthen wall at the northeast corner, 217 meters long, 12 meters wide, and 7 meters high. Despite over 2,600 years of human history, weathering, erosion, and natural weathering, it still retains a majestic presence. The upper layer of the wall reflects Qin Dynasty culture, the middle layer reflects Eastern and Western Zhou culture, and the lower layer reflects Shang Dynasty culture. In 1986, it was designated as a provincial-level key cultural relics protection unit by the People’s Government of Henan Province. In the early Eastern Han Dynasty, Emperor Guangwu Liu Xiu visited Nandun and built a platform and temple 100 meters north of the ancient city wall ruins, later known as the Guangwu Temple.
