 City
Wall of Xian is an extension of the old Tang Dynasty structure, as a result
of the wall-building campaign ordered by Zhu Yuanzhang, the first emperor
of Ming Dynasty (from 1370 A.D.- 1375 A.D). After the enlargement, the
city wall stands 12 meters (40 feet), 12-14 meters (40-46 feet) across
the top, 15-18 meters (50-60 feet) thick at bottom and 13.7 kilometers
(8.5 miles) in length with deep moats surrounding it. It boasts the most
complete city wall to have survived through China's long history.
The wall was built of earth, rammed layer upon layer during the early
time. The base layer was made of earth, quick lime, and glutinous rice
extract, tempered together. This made the wall extremely strong and firm.
Later, the wall was totally enclosed with bricks.
The Ming City wall encircles the city in a rectangle with one gate on
each side. On the wall, fortifications such as watch towers, ramparts,
(duo-kou) were built into a complex and well-organized system of defense.
There are total 98 ramparts on the wall and there are 120 meters distance
from each other- towers that extruding out from the main wall. On the
top of the rampart were 5984 2-metre- (7-foot-) high crenels called duo-kou.
On the upper part of the duo-kou were large openings used to watch and
shoot at attackers, and on the lower part were small openings, or loopholes,
through which defenders could also shoot. The distance between ramparts
is just within the range of arrow shot from either side, which allowed
soldiers to protect the entire wall without exposing themselves to the
enemy. Every several rampart on the wall has a sentry building of two
or three stories where soldiers were stationed.
 On
the four corners of the wall were watchtowers. The one at the southwestern
corner is round, probably after the imperial city wall of the Tang Dynasty,
but the other three are square-shaped. On top of the watchtowers, the
corner rampart, higher and larger than the ordinary ramparts, shows the
strategic importance of corners of the city wall.
The existing Ming City Wall has 4 gates as: the South Yongning (Eternal
Peace), the North Anyuan (Harmony Longevity), the West Anding (Harmony
Peace) and the East Changle (Eternal Joy). Built outside each gate was
a weng-cheng, a semicircular or polygonal parapet that shielded the gate
from direct assault. Zhenglou is a triple-eaved building 34.6 meters (114
feet) long) where generals used to direct their soldiers. On the outer
face were 48 openings from which missiles could be fired on a potential
enemy. Zhalou was built opposite to the Zhenglou with the suspense bridge
on the rear of the fort. The narrow tower - Jianlou where soldiers shoot
arrows was connected with Zhenglou by weng-cheng. From weng-cheng, access
ramps for horses lead to the top of the wall. There are all together 11
horse-passages around the city. The South Gate, to which visitors are
usually taken, is well preserved. Today you will find souvenir shops and
showrooms inside the gate structures. The West Gate has recently been
opened to the public.
After several restorations, the longest unbroken section is from the Western
Gate to the East Gate, a distance of approximately 5 kilometers (3 miles).
Cycling on top of the wall in this section, you will have a bird's eye
view of the city.
