The Xiangyang Ancient City Wall is located in Xiangcheng District, Xiangyang City, Hubei Province. Originally built during the Han Dynasty, it underwent several renovations from the Tang to the Qing Dynasties. The wall was initially roughly square, with a perimeter of 7331 meters, a maximum height of 10.84 meters, and a thickness of 11-14 meters. The overall structure includes trapezoidal cross-section walls and arched gates. The city wall has six gates on its four sides, each with a barbican or inner city, and corner towers at the four corners. Along the wall are watchtowers and beacon towers, and over 4000 crenellations are built. A moat surrounds the city, reaching a maximum width of 250 meters and an average width of 180 meters. On June 25, 2001, the Xiangyang Ancient City Wall was designated as a fifth batch of National Key Cultural Relics Protection Units by the State Council of the People's Republic of China. Speaking of the ancient city of Xiangyang, it inevitably evokes memories of Jin Yong's martial arts novels for a generation. The legendary stories of the heroes Guo Jing and Huang Rong defending the city and Yang Guo losing his arm all took place here. It was also a place where Yue Fei's army once fought.
