The report of Commissar Sun of the Shangqiu Institute of Cultural Relics and Archaeology is entitled "Archaeological Excavation Harvest and Preliminary Understanding of the Ancient City Wall of the Song Dynasty in Shangqiu".
The 2021 Archaeological Excavation Project of the Ancient City Wall of the Song Dynasty is the second archaeological excavation of the ruins of the Ancient City of the Song Dynasty.
The deepest part of the excavation has reached about 5 meters. The silt layer on both sides of the wall of the excavation area has been cleared, the top of the city wall junction has been completely exposed, 21 Ming and Qing tombs and 1 road have been cleared, and the collapsed building components and continuous green bricks no later than the middle of the Ming Dynasty have been revealed, which is speculated to be the bricks of the city wall.
According to the analysis of excavated relics and formation accumulation:
1. The city wall was abandoned due to a large flood, and it should be recorded in the literature that "in June (the fifteenth year of Hongzhi, that is, in 1502), the Yellow River broke through, the river entered the city, and the public and private houses disappeared." The Old City has never been" corroborated.
2. After the city wall was abandoned in the Ming and Qing dynasties, there were still some sections of the wall that retained the higher parts, and later became a cemetery.
3. Tang and Song porcelain pieces are mostly seen in the rammed earth layer at the top of the existing city wall, and there are no relics of the Ming Dynasty, and it is speculated that the ancient city of the Song Dynasty was built on a large scale during the Tang and Song Dynasties and was used by the Ming Dynasty, but it is not excluded that the city wall built in the Ming Dynasty was destroyed by a later period.
