GREAT WALL OF CHINA

The Great Wall of China was constructed over 2,000 years before, by Qin Shi Huangdi, the first emperor of China throughout the Qin (Ch'in) Dynasty (221 B.C - 206 B.C.). In Chinese the partition is called "Wan-Li Qang-Qeng" which entails 10,000-Li Long Wall (10,000 Li = about 5,000 km).

After subjugating and joining China from seven Warring States, the emperor attached and expanded four vintage fortification partitions along the north of China that began about 700 B.C. (over 2500 years ago). Armies were positioned along the partition as a first line of protecting against contrary to the invading nomadic Hsiung Nu tribes north of China
. Signal blazes from the Wall supplied early alert of an attack.

The Great Wall is one of the biggest construction building tasks ever completed. It extends over the hills of to the north China, winding north and northwest of Beijing. It is assembled of concrete, rocks and packed-earth. It was over 5,000 km (=10,000 Li) long. Its width extended from about 4.5 to 9 meters (15 to 30 feet) and was up to 7.5 meters (25 feet) tall.

During the Ming Dynasty (1368-1644), the Great Wall was enlarged to 6,400 kilometers (4,000 miles) and renovated over a 200 year time span, with watch-towers and cannons added.

The Great Wall can be glimpsed from EARTH
, but, opposing to legend, is not evident from the moon, as asserted by astronauts Neil Armstrong, Jim Lovell, and Jim Irwin
