Last updated 2026-11-16 — Nanchang Ancient City　　Located north of Nanchang Village, Shagou Town, Xuecheng District. It was the site of the ancient "Chang" settlement during the Spring and Autumn and Warring States periods. By the Western Han Dynasty, Jianyang County was also established here (in the fourth year of Emperor Xuan of Han’s Ganlu era, Marquis Jing Wei Wan was enfeoffed at Jianling). The ancient city is roughly rectangular, measuring about 550 meters from east to west and 440 meters from north to south. Currently, only a section of earthen mound remains on the northern part of the eastern wall, while the rest has been leveled. In 1980, it was designated as a municipal-level key cultural relics protection unit by the Zaozhuang Municipal People's Government, and in 2006, it was listed as part of the third batch of provincial-level cultural relics protection units by the Shandong Provincial People's Government.
