After unifying six states in northern China in 221 B.C.,
the first emperor of the Qin Dynasty issued an order that the walls originally
built be reinforced and linked together for defense against attack by the
slave-owner regime in the northern part of China. This is how the well-known
3,600-mile Great Wall came into being and has played a significant role in
protecting the economic and cultural developments in the central plain area for
some 2,000 years.
As you can imagine, the Great Wall has been restored and
re-inforced during successive dynasties, most during the Ming Dynasty. This
dynasty devoted huge amounts of manpower and resources to the restoration
project, taking a total of over 100 years to complete.
Some of the stone slabs in the wall, which are made from
local materials, are as heavy as one ton. Considering the condition of the
time, you can imagine how extremely difficult the project was.
Because of the high quality of its construction, most of
the Great Wall built during this time still stands.
The section at Badaling, restored in 1957 for visitors,
is typical in structure of what the entire wall once was. It has an average
height of 26 feet, is 22 feet wide at the bottom and 19 feet wide at the
top.
Every 200 -350 yards, battlements were built for watching
and shooting. The guardhouses built at intervals were used as sentry posts and
headquarters for soldiers. Beacon towers were built at commanding points at
each side of the wall, with smoke used in the daytime and fire at night, in
case of emergency.
The Great Wall is also wide enough to permit two
automobiles to pass on it at one time. The project is so huge that astronauts
can see it from miles up.
See you again soon, I hope.
