The Xi'an City Wall is not only the most complete city wall that has survived in China, but it is 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.
The military defense facilities here including the city wall, city moat, drawbridges, watchtowers, corner towers, parapet walls and gate towers once made up a complete city defense system.
Many sections have since been destroyed and the city walls are incomplete. The 14 kilometers of wall does not stretch around the entire city. You can get up on the walls at the east of the railway station and at the south gate adjacent to the provincial museum.
