Recent studies by the State Directorate of Archaeology, Topography and Cartography China discovered that the Great Wall is even longer than previously thought. The Great Wall of China belongs to the select group of old buildings (like the pyramids of Giza, Machu Picchu and the Roman Colosseum, etc.) whose performance in such distant times it seems impossible to imagine in these modern times. So each new finding in the environment generates an echo transnational and touch fibers in history. This happened when the State Bureau of Archaeology, China Surveying and Mapping revealed that the zigzag snake stone has about 2500 miles more than I thought. Built in several stages from the sixth century BC, the Great Wall is the greatest symbol of the region, now official length of 8851 kilometers.

Towers in the Mist:

The wall dazzles the thousands of visitors arriving each year. The scale placed on mountain ridges, rivers and penetrating passes over the valleys, hiding its outline under intermittent mist. In this compilation of looming clouds from time to time the structure of the castle of some 25 thousand towers. Its route extends east from the Bohai Sea (Bay of the mythical Yellow Sea) to the Gobi Desert in the west, across 156 districts within 10 provinces. Although the dimensions vary in different sections, the average height of the walls varies between seven and eight meters high with a base of six feet thick. In its course the wall is posted by the communication towers, fortified gates and defensive ramparts. It has three steps: the citadel of Jiayu, which officially kicks off the Great Wall, is of 1372 and consists of a double wall of brick and earth square, more than 700 meters. The Shanhaiguan was another important step on the fortress wall, located near the eastern edge. The last step is Juyong, which had the task of defending the hills of the capital, Beijing. Some accounts say that thousands of workers who contributed to the construction of the different stages and steps used the materials available near the surroundings: stones with a high degree of metal (including silver) near Tian Ling Liao; limestone near Beijing, and granite, ceramics and bricks baked in the East.

Technology Tip:

The new section detected was the most important discovery of the planning project of the Department of Chinese national treasures, which was launched in early 2007 for their protection. Advanced Satellite tracking and navigation tools on the end of 2008 revealed the existence of some sections ignored in rugged mountains and deserts of Chinese soil. «The works of modern road and rail have affected,» said its director, Shan Qixiang. While you can see huge sections, only a small percentage is up (20% in fair condition and 30% with many ruins), while the rest has been eroded and / or destroyed by man over time. The Great Wall traverses provinces including Liaoning, Hebei, Shanxi, Gansu and Shaanxi as well as the Inner Mongolia Autonomous Region, Tianjin and Beijing.
