The Xian City Wall is not only the most complete city wall that has survived in China, but its also one of the largest and most complete ancient military systems of defense in the world. The city walls here were actually built on the fortifications of the Tang Forbidden City.

Located in the central area of Xi’an city, the Xi’an City Wall which built in Ming Dynasty stands 12 meters high. It is 12- 14 meters across the top, 15-18 meters thick at bottom and 13.7 kilometers in length. It is divided into several important parts such an the rampart, the gate tower, the suspend bridge, the watch tower, the moat and so on. The Ming Dynasty City Wall formed a complex and well-organized system of defense. The city wall itself is a true display of the ability and wisdom of the working people in ancient times. It provides invaluable and substantial material for the study of the history, military science, and architecture of the Ming Dynasty.
