Ancheng City Wall

　　 The wall was initially built in the early Ming Dynasty and reinforced with stone in the 33rd year of the Jiajing reign (1554), with subsequent renovations over the years. The city has an elliptical layout, with a perimeter of approximately 6,000 meters. The ancient architecture within the city was largely destroyed by Japanese bombing during the War of Resistance against Japan, leaving almost no remains. The surviving sections of the wall stand 4–6 meters high and are 5 meters thick. There are three gateways — southern, western, and northern — all featuring arched vaults. Besides its defensive role, the wall also helped prevent flooding.

　　 In 2006, the Ancheng City Wall was designated as a National Key Cultural Relics Protection Unit by the State Council, recognized as a historical architecture site from the Ming and Qing dynasties.
