The Great Wall is a symbol of Chinese civilization, and one of the wonders that the Chinese people have created. Badaling Great Wall, the most representative part, was promoted as a key national cultural relic, protected under the approval of the State Council in 1961. In 1988, it was enlisted in the World Cultural Heritage Directory by UNESCO. July 7, 2007 has once again witnessed the worldwide reputation that the Great Wall gained: it was listed among the New Seven Wonders of the World.
Badaling Great Wall is situated in Yanqing County, over 70 kilometres (43 miles) north of Beijing. It is the most well-preserved section of the Great Wall, built during the Ming Dynasty (1368-1644). This section with an average altitude of over 1,000 meters (3,282 feet) is the outpost of the Juyongguan Pass. The mountain slope is very steep and the roads are tortuous. These features made it a military stronghold. Badaling Great Wall is like a strong dragon winding its way along the mountain ranges.
The Great wall originally functioned as a fortification. As early as the Qin Dynasty, Qinshihuang, the first emperor of Qin Dynasty unified the whole nation and began to build the Great Wall to protect China’s borders from the intrusion of the northern nomadic tribes. Most parts of the preserved Badaling Great Wall were built and reinforced during the Ming Dynasty to defend the capital against the intrusion of these Mongolian people. The structure of the wall consists of huge bar-stones and bricks. The inside of the wall has been formed by tampering earth and small stones, which makes the wall very firm and strong. Internally, the wall is about six meters (20 feet) wide, which would allow horses to gallop five abreast. A number of small holes have been drilled on the wall to allow archers to shoot arrows. There is a barrel-drain and a moat both inside and outside the wall. In a word, military fortification has been paramount in the consideration of every wall detail.
The signal fire platforms were an important part of the whole fortification of ancient China. A signal fire platform is actually a blockhouse that was built on the top of the wall. It was used to send warning signals. Since the Ming Dynasty, the amount of smoke and gunfire released conveyed specific military information about the enemy. One release of smoke with one shot of gunfire signified 100 enemies; two smoke releases with two shots of gunfire meant 500 enemies; three smoke releases with three shots of gunfire indicated more than 1,000 enemies. Once one signal platform fired a beacon, the others would follow likewise so as to alert the command as to the strength of the enemy.
As a landmark erected at the top of a group of mountain ranges, Badaling Great Wall has also witnessed many significant historic events. The first emperor of the Qin Dynasty toured there, Yuan Taizu, the first emperor of Yuan Dynasty (1271-1368) passed the Badaling Great Wall and took control over the whole of China. Empress Cixi fled from there to the western part of China in 1900 when an alliance of eight western countries invaded Beijing. At present, Badaling Great Wall stands still there recording the hardship and bitterness that Chinese people have endured in the past 2000 years. It is a priceless cultural heritage of humanity.
Badaling Great Wall was the earliest part of the great Wall opened to tourists. It has drawn tens of millions of tourists both from home and abroad. More than 370 foreign leaders and celebrities have visited there.
