Taizhou City Wall, famously called the Jiangnan Great Wall, sits in Linhai City of Taizhou, Zhejiang Province. Construction started in the Eastern Jin Dynasty, with expansions in the Tang and Song dynasties and renovations in Ming and Qing periods. The surviving wall stretches 4,730 meters, uniquely designed for dual purposes: military defence against invaders and flood prevention along the Lingjiang River. It features semi-circular barbicans and hollow enemy towers improved by Qi Jiguang, the renowned Ming general. Highly regarded as the blueprint for the northern Ming Great Wall, it was designated a Major Historical and Cultural Site Protected at the National Level in 2001 and included on China’s World Heritage Tentative List. It is the highlight of the national 5A Ancient City of Taizhou Cultural Tourism Area.
