Great Wall of China

Wikipedia

This article discusses the man-made structure. For the largest known Large-scale structure of the cosmos|super-structure in the universe, see Great Wall (astronomy).

The Great Wall of China (Traditional Chinese|TC: 長城; Simplified Chinese|SC: 长城, Pinyin: Chángchéng), also known in China as the Great Wall of 10,000 Li#Notes|¹ (Simplified Chinese|SC: 万里长城, Pinyin: Wànlĭ Chángchéng), is an ancient China|Chinese fortification built from the end of the 15th century until the beginning of the 16th century, during the Ming Dynasty, in order to protect China from raids by the Mongols and Turkic tribes. It was preceded by several walls built since the 3rd century BC against the raids of Ethnic groups in Chinese history|nomadic tribes coming from areas now in modern day Mongolia and Manchuria.

The Wall stretches over a formidable 1 E6 m|6,700 km (4,200 miles), from Shanhai Pass on the Bohai Gulf in the east, at the limit between China proper and Manchuria, to Jiayu Pass (嘉峪关) in western Gansu province in the west, at the limit of the Gobi Desert and the oases of the Silk Road.

History

Image:GreatWallNearBeijingWinter.jpg|thumb|250px|The Great Wall in the winter, near Beijing

The first major wall was built during the reign of Qin Shi Huangdi|The First Emperor, the main emperor of the short-lived Qin dynasty. This wall was not constructed as a single endeavor, but rather was created by the joining of several regional walls built by the Warring States Period|Warring States. It was located much further north than the current Great Wall, and very little remains of it. A defensive wall on the northern border was built and maintained by several dynasties at different times in Chinese history. The Great Wall that can still be seen today was built during the Ming Dynasty, on a much larger scale and with longer lasting materials (solid stone used for the sides and the top of the Wall) than any wall that had been built before. The primary purpose of the wall was not to keep out people, who could scale the wall, but to insure that semi-nomadic people on the outside of the wall could not cross with their horses or return easily with stolen property.

There have been four major walls:

# 208 BC (the Qin Dynasty)
# 1st century BC (the Han Dynasty)
# 1138 - 1198 (the Five Dynasties and Ten Kingdoms Period)
# 1368-1620 (from Hongwu Emperor until Wanli Emperor of the Ming Dynasty)

The Ming Dynasty Great Wall starts on the eastern end at Shanhai Pass, near Qinhuangdao, in Hebei Province, next to Bohai Gulf. Spanning nine provinces and 100 counties, it ends on the western end at Jiayu Pass located in northwest Gansu Province. Jiayu Pass was intended to greet travelers along the Silk Road. Even though The Great Wall ends at Jiayu Pass, there are many watchtowers (烽火台 fēng huǒ t?i) extending beyond Jiayu Pass along the Silk Road. These towers communicated by Smoke signals|smoke to signal invasion.

The Kokes Manchus crossed the Wall by convincing a crucial general Wu Sangui to open the gates of Shanhai Pass and allow the Manchus to cross. Legend has it that they took three days for the Manchu armies to pass. After they conquered China, the Wall was of no strategic value as the people who the Wall was intended to keep out were ruling the country (becoming the Qing Dynasty).

The government ordered people to work on the wall, and workers were under perpetual danger of being attacked by brigands. Because many people died while building the wall, it has obtained the gruesome title, "longest cemetery on Earth".

Condition

While some portions near tourist centers have been preserved and even reconstructed, in most locations the Wall is in disrepair, serving as a playground for some villages and a source of stones to rebuild houses and roads. Sections of the Wall are also prone to graffiti. Parts have been bulldozed because the Wall is in the way of construction projects. The Great Wall Society of China works to preserve the Wall. Through June 2003, the Chinese government still had no laws written to protect the Wall nationwide. However, Beijing has enacted local legislation which would prohibit visits to the "wild Great Wall" or parts not open to the public; this has been in force since August 2003.

Watchtowers and Barracks

The wall is complemented by defensive fighting stations, to which wall defenders may retreat if overwhelmed. Each tower has unique and restricted stairways and entries to confuse attackers.

Barracks and administrative centers are located at larger intervals.

Specialized defense weapons

In addition to the usual miltary weapons of the period, specialized wall defense weapons were used. Reproductions of these weapons are displayed at the wall.

Materials

The materials used are those available near the site of construction. Near Beijing the wall is constructed from quarry|quarried limestone blocks. In other locations it may be quarried granite or fired brick. Where such materials are used two finished walls are erected with earth and rubble fill placed in between with a final paving to form a single unit. In the extreme western desert locations where good materials are scarce the wall was constructed from dirt rammed between rough wood tied together with woven mats.

Recognition

The Wall is sometimes included in lists of the "Seven Wonders of the Modern World," but was of course not one of the classical Seven Wonders of the World recognized by the ancient Greece|Greeks.

The Wall was made a UNESCO World Heritage Site in 1987.

There is a great debate about how visible the wall is in space. 1938, Richard Halliburton's Second Book of Marvels said the Great Wall is the only man-made object visible from the moon. This persisted and assumed urban legend status - sometimes even entering school textbooks. If taken to mean that the Great Wall can literally be seen, with the unaided eye, from the distance of the moon: it is simply untrue. It's visibility from near earth orbit is questionable.

One Space Shuttle program|shuttle astronaut reported that "we can see things as small as airport runways but the Great Wall is almost invisible from only 180 miles (290 km) up." Astronaut William Pogue thought he had seen it from Skylab but discovered he was actually looking at the Grand Canal of China|Grand Canal near Peking. He spot the Great Wall with binoculars, but said that "it wasn't visible to the unaided eye." Recently, Chinese astronaut Yang Liwei said he couldn't see it at all. An Project Apollo|Apollo astronaut said no human structures were visible at a distance of a few thousand miles. But these astronauts don't have the last say, since the debate is ongoing.

From low earth orbit, about a thousand times nearer than the moon, it may be visible under favorable conditions. Features on the moon that are dramatically visible at times can be undetectable on others, due to changes in lighting direction. The Great Wall is only a few meters wide - sized similar to highways and airport runways.

Veteran U.S. astronaut Gene Cernan has stated: "At Earth orbit of 160 km to 320 km high, the Great Wall of China is, indeed, visible to the naked eye." Ed Lu, Expedition 7 Science Officer aboard the International Space Station, adds that, "...it's less visible than a lot of other objects. And you have to know where to look."

Ultimately though, the idea that the Great Wall is somehow more visible than anyother similarly sized, man-made object is a myth.
