The city wall of Xi’an is the largest and now most complete city wall in China. Thanks to extensive renovations since the 1980s, the city wall is today walkable along the entire length and forms a rectangular ring around the old town of Xi’an.
The city wall was built in the 14th century during the Ming Dynasty, under the rule of the conqueror Zhu Yuanzhang. It covers an area of approximately 12 km². The walls in the north and south are about 3.5 kilometers long, the east and west sections about 2.5 kilometers.
There is a view tower on each of the four corners. The one at the southwestern corner is built around, perhaps on the model of the Imperial city wall of the Tang Dynasty, but the other three are square.
The southern gate and the northern gate are two main entrances to the inner city. The city itself is seamlessly aligned along the wall. In 2008, the city wall of Xi’an was nominated as a World Heritage Site by UNESCO.
