The Great Wall of China was built 2,000 years ago
during the 14th through the 17th centuries. It stretched over
5,000km and later expanded to 6,400km. In most places the wall
was 4.5 to 9 meters (15 To 30ft.) tall. It is the largest
structure ever built.
The Great Wall of China has a very
long and interesting history. During the dynastic period, five
major walls have been built.
1. 208bc (the Qin Dynasty)
2. 1st century BC (the Han dynasties)
3. 1138-1198 the 5 dynasties and 10 kingdom’s period
4. 1368-1620 (From Hongwu Emperor until Wanli Emperor
5. The Ming Dynasty wall (it stretched over nine provinces and 100 counties).
government ordered people to work on the wall. Workers on the
wall were under perpetual danger of being attacked by brigands.
Because many people died building the wall, it earned a nickname - “The
long graveyard. Despite the common rumor, no workers were buried
in the wall because it would weaken the structure. Instead the bodies
were buried nearby. Most of the historic wall is not well
preserved, and today, it is very prone to vandalism. The primary
purpose of the wall was not to keep out people who could scale it, but
to insure that semi-nomadic people on the outside of the wall could not
cross with their horses or return easily with stolen property. It
protected China from Mongols and from Turkic tribes.
Great Wall can be seen from orbit, although an officer aboard ISS
(International Space Station) stated the wall is harder to see than
some other things. One of the reasons it’s harder to see
The Great Wall than other things is because it’s only a few meters
wide. Another reason is that it’s also the same color as the soil
around it, and it looks similar to runways and highways. A photo
from ISS confirms that the Great Wall can be seen with the naked eye;
you just need to know where to look.
