This ancient city was the seat of a highly cultured civilization during the Ming Dynasty. Today, the remains of the 7 m high Ming City Walls run along the banks of the Han Jiang, defining the eastern boundary of the old city center. Extending up to Huangcheng Lu in the west, the old city is Chaozhou’s most fascinating quarter, where its historic past is visible on streets such as Zhongshan Lu and Jiadi Xiang with its well preserved Qing Dynasty architecture. To the north of Jiadi Xiang is Kaiyuan Si, an active Buddhist temple founded in AD 738, with pretty courtyards and several colorful halls, one of which has a gorgeous vaulted ceiling. The grand Guangji Men along the city wall has steps leading up to a trail along the top of the wall. Across the river is the 10th-century temple Hanwen Gong Ci, and downstream is the slowly crumbling Ming dynasty pagoda Fenghuang Ta.
