When you come to Badaling, you should not miss China Great Wall Museum. It is a special museum which reflects the history and current situation of Great Wall. The appearance of the museum is very striking. It is built in a shape of the wall. Visitors can see the imitating designs such as beacon towers, passes and watch towers everywhere in it, as if stand in a real wall.

Opened formally on Sep.6 1994, the museum covers an area of 3,200 square meters (3,827 square yards) and has nine exhibition halls. The basic displays are mainly composed of seven parts divided by different topics like "Great Wall of All Dynasties", "Great Wall of Ming Dynasty", "The Defensive Function of the Great Wall and its System", "Wars", "Economic and Cultural Exchanges between People on Both Sides of the Great Wall" and "Culture and Art".

The Great Wall was started to be built in the Spring and Autumn Period over 2,500 ago to defend themselves against other feudal lords and ethnic groups. The feudal states linked a series of small forts into long defense works. As a result, it emerged in China.

The Great Wall of Qin Dynasty (221 BC-206 BC) was built by the first unified multi-ethnic feudal state in Chinese history. The Qin wall appeared after the unification of China as a country under centralized rule. In the reign of Emperor Qin Shihuang, to defend the country from the Huns, the walls built on the northern borders of the states of Qin, Zhao and Yan in the Warring States Period were connected, forming what is known as "the ten-thousand-li Great Wall (1 li=500 meters=547 yards)". The Great Wall of Han Dynasty (206BC-220) was the longest in length in Chinese history. To defend the country against the Huns and other northern nomadic peoples, the Han Dynasty built the wall and bulwarks, forts, sentry booths and beacon towers along its border.
