The vanishing of China’s Great Wall
The Great Wall was China’s most solid line of defence during much of its long history, but now, it is unable to resist wind erosion and commercial alienation. Those sections outside people`s focus gradually disappear due to weather and human activities.
August 6, 2012, Dajingmen section in Zhangjiakou City, Hebei Province had a 30 meters serious collapse for In addition to rainfall, another reason is that this section has been out of repair for long years.
The existing ruins of the Ming Great Wall were built in the 14th century, west to Jiayuguan, Tiger Mountain, east of Liaodong length of 8851.8 km, the average height of 6-7 meters wide and 4 to 5 meters. The picture shows Ming Great Wall beacon towers in Wuwei City, Gansu Province.
According to the bureau statistic, about one third of the Great Wall built during the Ming Dynasty (1368-1644) have disappeared. There are two main factors, natural power and human activities, Natural factors include earthquakes, landslides, wind and rain erosion, human factors include traffic and other construction projects, production and life activities, inappropriate development and repairs.

Great Wall ruins can be divided into two categories – scenic spots and non-scenic spots, Great Wall sections like Badaling, Shanhaiguan and Jiayuguan have been well known, while total length of these sections is only 1000 km, the main sections in steep mountains, desert and wasteland are unmanaged.

The China government invested a huge amount of money to those famous sections like Badaling and Shanhaiguan. While the sections exposed to the wilderness disappeared in a variety of natural factors and human activities.
Tourism can bring the revenue, but it also brings the destruction of tourism resources. In 2012, the British “Guardian” reviewed the world’s destroyed famous tourism attractions, the Great Wall of China, the Great Barrier Reef in Australia and United Kingdom Stonehenge are on the list.
