One of the Seven Wonders of
the World, the Great Wall of China is a man-made structure that was constructed
over two thousand years ago and took about 100 years to complete. The vastness
of this project brings to light the immense capabilities of man.
The Great Wall of China was
built by Qin Shi Huangdi over 2,000 years ago, the first emperor of
China. In Chinese the wall is called "Wan-Li Qang-Qeng" which means
10,000-Li Long Wall (10,000 Li = about 5,000 km).
The Great Wall of the Ming
is, not only because of the ambitious character of the undertaking but also the
perfection of its construction, a masterpiece. The wall constitutes, on the
vast scale of a continent, a perfect example of architecture integrated into
the landscape. During the Chunqiu period, the Chinese imposed their models of
construction and organization of space in building the defence works along the
northern frontier. The spread of Sinicism was accentuated by the population
transfers necessitated by the Great Wall.
Visibility from Earth Orbit or Moon ?????
It’s a controversial issue. NASA
says, "The Great Wall can barely be seen from the Shuttle, so it would not
be possible to see it from the Moon with the naked eye."
Furthermore, from the moon,
even the continents are barely visible.
