The
Great Wall as it exists today was built mainly in the Ming Dynasty
(1368 - 1644). It was an ambitious project and took over 100 years
to complete. The walls of this period were well designed and known
for their unique configuration and effective defense system. Extending
from the Yalu River in Liaoning Province to the eastern bank of
the Taolai River in Gansu Province, Ming's Great Wall winds its
way from east to west through present Liaoning, Hebei, Tianjin,
Beijing, Inner Mongolia, Shanxi, Shaanxi, Ningxia and Gansu Provinces
or areas.
Research has shown that Ming's emperors were busy with the construction
of this wall throughout their reign. After seizing political power
from rulers of the Yuan Dynasty (1271 - 1368), the emperors had
to battle desperate Yuan forces in the north and stop the threat
of invasion from other northern ethnic tribes such as Nuzhen, Dada
and Wala. To resist these outside forces and protect their citizens,
every emperor of the Ming Dynasty spared no effort in building,
fortifying, extending and eventually completing the Great Wall.
The design of the Ming Wall was well thought out. For example,
Xuanfuzhen Great Wall in Beijing, due to its strategic position,
was built in the unique style of double lines, inner and outer,
to strengthen its defensive ability. A total of six passes were
built. The inner passes were Juyongguan
Pass, Zijingguan
Pass and Daomaguan Pass, and the outer passes were Pianguan
Pass, Ningwuguan
Pass and Yanmenguan Pass.
These passes controlled entries and exits into the areas and are
secured by gates. Watch towers, signal towers, fortresses, and observation
posts serve as additional reinforcements. The Ming Wall was further
divided into nine zones, each controlled by a garrison, called 'zhen'
in Chinese. Two more garrisons were added later, making a total
of eleven garrisons.
This ensured the security of the capital.
Following the topographies of the land through which it travels,
this ancient wall looks like a long winding dragon. To get a rough
idea of the size: if all its stones, bricks, and earth are used
to build a city wall of 1.1 yards high and 5.5 yards wide, the
total length of this wall will circle the earth more than once.
Today, remnants of this huge wall stand as a witness to the sacrifices
of the ancient builders and the wisdom of its designers. It is
perhaps one of the greatest architectural achievements of men.
