Amazing Places: Great Wall of China

Location:

Great wall of China is located between from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia.

 

History:



The Great Wall of China was built over more than two thousand years by Qin Shi Huangdi (the 1st emperor of China )

Qin Shi Huangdi (the 1st emperor of China )

Construction on the first section began between the 7th and 6th century BC, and the last work on the wall was done between the 14th and 17th centuries.

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 China is a series of stone and earthen fortifications in China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire from Xiongnu attacks during the rule of successive dynasties.

The primary purpose of the wall was not to keep out people, who could scale the wall, 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.

Several walls, referred to as the Great Wall of China, were built since the 5th century BC.
One of the most famous is the wall built between 220206 BC by the first Emperor of China, Qin Shi Huang; little of it remains; it was much farther north than the current wall, which was built during the Ming Dynasty.

It has been estimated that somewhere in the range of 2 to 3 million Chinese died as part of the centuries-long project of building the wall.

The first major wall was built during the reign of the First Emperor, the main emperor of the short-lived Qin dynasty. This wall was not constructed as a single endeavor, but rather was created by the joining of several regional walls built by the Warring States.

It was located much further north than the current Great Wall, and very little remains of it.

The constructors who died working were buried inside the wall.

Before the use of bricks, the Great Wall was mainly built from earth, stones, and wood.

Specialties:



The Great Wall stretches to over 6,700 km (4,160 miles) in total.

At its peak, the Ming Wall was guarded by more than one million men.

Many western sections of the wall are constructed from mud, rather than brick and stone, and thus are more susceptible to erosion. It has been estimated that more than 60 kilometers (37 mi) of the wall in Gansu province may disappear in the next 20 years, due to erosion from sandstorms.

Near Beijing the wall is constructed from quarried limestone blocks and in some areas the blocks were cemented with a mixture of glutinous rice and egg white.

The Wall is included in lists of the "Seven Medieval Wonders of the World" and was made by UNESCO A World Heritage Site in 1987.

It is not visible from space by unaided eyes contrary to the belief that Great Wall can be seen by space.Still, the apparent width of the Great Wall from the moon is the same as that of a human hair viewed from 2 miles away.

The wall is complemented by defensive fighting stations, to which wall defenders may retreat if overwhelmed. Each tower has unique and restricted stairways and entries to confuse attackers.

The wall also has watch towers at regular intervals, which were used to store weapons, house troops, and send smoke signals.
