The Great Wall of China is one of the seven wonders. It is about 6,400km long and it was built mare than 2000 years ago. It is also called “the longest cemetery on Earth”. The Great Wall of China started building 7th century B.C.
The Great Wall was built when seven powerful states appeared at the same time, to defend themselves. At that time the wall was 3,107 miles and each part of wall belonged to different part of the states.In 221 B.C the Emperor Qin Shi Huangdi ordered to connect the walls (built by all the states) also he added a part of his section because he was afraid from the northerns- that were called Xiongnu. Qin wall was formed which started from the east of today’s Liaoning Province and ended at Lintao, Gansu Province.
The ruler of the Han Dynasty was Han Wudi ( “ Martial emperor of Han” ). He said to design the project of the Great Wall in 127 B.C. The Wall extended to the territories to the present day Mount Yinshan of Inner Mongolia. The main reason for contributing to this project was to be secure from the north- from the Gobi. This was the main reason for all of the efforts from every Dynasty to the making of this wall.
The ruler of Ming Dynasty was Yong Le. He built large monuments and strengthened the Wall. The Great Wall of China was mostly built during the Ming Dynasty. The Wall started from the Yalu River in Liaoning Province and ended at the eastern bank of the Taolai River in Gansu Province.
BaDaLing Section was built in the beginning of the rule of Ming Dynasty. It is 7.8 meters in height and it is 5 meters wide on the top. 10km south of Badaling section there is a gateway, northwest of Beijing. The gateway is called the Pass of Conscripted Laborers.
Mutianyu Section is located 70km northeast of Beijing. It is older than the Badaling Section. The Wall was built in the mid-6th century.It is specialy made to protect the invaders from the north. The wall is 7-8 meters high.
Huangyanguan Section was built under the rule of the Ming dynasty. It is 41km long but it’s not as crowded as on the other sections. Huanyanguan Great Wall runs on rigid mountains to the north of Ji County.
There are some guards standing near the Great Wall of China and there are a couple of security camera s. In the watchtowers weapons are stored for emergency purposes . But the protection is not major. Some parts of bricks have fallen down and it is not clean. This issue has risen up several times but this did not result in anything . There should be laws made for the safety of the Great Wall. It can be concluded that the security of the Great Wall is not as tight.
Astronauts found out that the Great Wall of China can be seen from the space shuttle. Some people have believed that the Great Wall can be seen from the moon but it is kind of impossible. From the Moon, Earth look s like a sphere which is greenish-blue in colour .
