Built more than 2 thousand years ago, the great wall of china defended the country from invasions by enemy towns. Currently it is a World Heritage Site that can be easily seen from space via satellite.
Even the astronauts of the International Space Station they can photograph it, and the view is simply impressive.
It is practically a serpentine dragon that for centuries served as protection for China, with the wall divided between two great lines, the south and the north. Many fragments are found near Beijing, the capital.
Originally measured about 21,200 kilometers, although currently only 30% of it is preserved. On average, it is 6-7 meters tall and 4-5 meters wide.
The Mongol archers, most feared by the Chinese, couldn’t do much without their horses. Therefore, the Great Wall of China prevented them from assaulting the country.
The brick and stone work is classified as a miracle in the history of ancient architecture, since adding all the sections of the wall, built in different dynasties, the length is enormous.
The Great Wall of China, from a masterpiece of military engineering to a World Heritage Site
Each defense tower had a garrison of between 30 and 50 men, according to National Geographic, who served four-month shifts. In the tower, the soldiers lived, keeping their supplies and food.
Living conditions were harsh, as the soldiers were exposed to the wind and cold, often without clothing or even food.
But what was once a masterpiece of military engineering, since 1987 it is listed by UNESCO as a World Heritage Site. Thousands of visitors come to the site to be photographed and to enjoy the landscape, becoming part of history.
