Ganzhou City Wall, Ancient fortification in Ganzhou, China.

The Ganzhou City Wall is a fortification of granite and brick that extends around the city center with several gates and watchtowers. The structure displays typical features of Chinese defensive architecture with various preserved sections that can be walked today.

The wall was first built in 349 under the Eastern Jin, when governor Gao Yan of Nankang raised an earthen rampart. Under the Northern Song, between 1068 and 1077, it was rebuilt in brick and stone. In 1958 the southern stretch from Baisheng Gate via Zhennan Gate to Xijin Gate was demolished, leaving 3,664 metres along the river.

The wall displays building methods typical of Chinese fortress architecture visible in its preserved sections today. It reflects the military and administrative needs that shaped daily life in a fortified city of that era.

Access is possible through various sections throughout the year, with the best views from the higher parts of the structure. Comfortable shoes are recommended since the paths can be uneven and a full walk takes time.

The wall's core is rammed earth faced with brick and stone, not granite throughout. A 1990 survey found surviving Song sections: 25.25 m of stone wall, 19.80 m of brick wall and a 41 m Southern Song brick foundation at the Yangjiyuan. Many bricks carry reign marks such as Xining and Shaoxing, rare on Chinese city walls.
