The Great Wall of China is one of the most magnificent structures of the world and has a place in the 7 wonders of the world. A large part of the wall borders China from Mongolia through the Gobi desert and the wall also acts as a border control measure along the silk route in ancient times. The archeological survey of the wall concludes that it is a whopping 8850 km long.
The Great Wall is a series of fortifications made during the ancient times by powerful Chinese dynasties to protect their kingdoms from immigration and emigration of people. The wall also acted as a protection from external threats from other dynasties. To further enhance the protectoral aspect of the wall, many barracks, garrison stations, watch towers etc have been built along the wall to check foreign intrusions.
The wall was comprehensively built by the Qin Dynasty in 221 BC and is one of the best tourism places in China. The Great Wall has been given the United Nations World Heritage Site status since 1987.
