Several walls were being built from as early as the 7th century BC;BOOK, The New York Times Guide to Essential Knowledge: A Desk Reference for the Curious Mind, The New York Times with introduction by Sam Tanenhaus, St. Martin's Press of Macmillan Publishers, 2011, 978-0-312-64302-7, 1131, Beginning as separate sections of fortification around the 7th century B.C.E and unified during the Qin Dynasty in the 3rd century B.C.E, this wall, built of earth and rubble with a facing of brick or stone, runs from east to west across China for over 4,000 miles., these were later joined together and made bigger by Qin Shi Huang (220–206 BC), the first Emperor of China. Little of that wall remains.WEB,weblink Great Wall of China, Encyclopædia Britannica, Large parts of the fortification system date from the 7th through the 4th century BC. In the 3rd century BC Shihuangdi (Qin Shi Huang), the first emperor of a united China (under the Qin dynasty), connected a number of existing defensive walls into a single system. Traditionally, the eastern terminus of the wall was considered to be Shanhai Pass (Shanhaiguan) in eastern Hebei province along the coast of the Bo Hai (Gulf of Chihli), and the wall's length—without its branches and other secondary sections—was thought to extend for some {{convert, 4,160, mi, km, flip, on, .}} Later on, many successive dynasties have repaired, maintained, and newly built multiple stretches of border walls. The most well-known of the walls were built during the Ming dynasty (1368–1644).Apart from defense, other purposes of the Great Wall have included border controls, allowing the imposition of duties on goods transported along the Silk Road, regulation or encouragement of trade and the control of immigration and emigration. Furthermore, the defensive characteristics of the Great Wall were enhanced by the construction of watch towers, troop barracks, garrison stations, signaling capabilities through the means of smoke or fire, and the fact that the path of the Great Wall also served as a transportation corridor.The frontier walls built by different dynasties have multiple courses. Collectively, they stretch from Dandong in the east to Lop Lake in the west, from present-day Sino-Russian border in the north to Qinghai in the south; along an arc that roughly delineates the edge of Mongolian steppe. A comprehensive archaeological survey, using advanced technologies, has concluded that the walls built by the Ming dynasty measure {{convert|8850|km|mi|abbr=on}}.

Names

The collection of fortifications known as the Great Wall of China has historically had a number of different names in both Chinese and English.In Chinese histories, the term "Long Rampart(s)" (長城, changcheng) appears in Sima Qian's Records of the Grand Historian, where it referred both to the separate great walls built between and north of the Warring States and to the more unified construction of the First Emperor.{{sfn|Waldron|1983|p=650}} The Chinese character }}, meaning city or fortress, is a phono-semantic compound of the "earth" radical }} and phonetic }}, whose Old Chinese pronunciation has been reconstructed as *deÅ‹.WEB, Baxter, William H. & al.,weblink Baxter–Sagart Old Chinese Reconstruction, Version 1.1, University of Michigan, Ann Arbor, September 20, 2014, January 22, 2015, It originally referred to the rampart which surrounded traditional Chinese cities and was used by extension for these walls around their respective states; today, however, it is much more often the Chinese word for "city".See Lovell 2006, p. 25The longer Chinese name "Ten-Thousand Mile Long Wall" (萬里長城, Wanli Changcheng) came from Sima Qian's description of it in the Records, though he did not name the walls as such. The {{sc|ad}} 493 Book of Song quotes the frontier general Tan Daoji referring to "the long wall of 10,000 miles", closer to the modern name, but the name rarely features in pre-modern times otherwise.{{sfn|Waldron|1990|p=202|ps=.

However, this use of "ten-thousand" (wàn) is figurative in a similar manner to the Greek and English myriad and simply means "innumerable" or "immeasurable".BOOK, Lindesay, William,weblink The Great Wall Revisited: From the Jade Gate to Old Dragon's Head, 21, Wuzhou Publishing, Beijing, 2007, 978-7-5085-1032-3, Because of the wall's association with the First Emperor's supposed tyranny, the Chinese dynasties after Qin usually avoided referring to their own additions to the wall by the name "Long Wall".{{sfn|Waldron|1983|p=651}} Instead, various terms were used in medieval records, including "frontier(s)" (}}, sāi),{{sfn|Lovell|2006|p=15}} "rampart(s)" (}}, yuán),{{sfn|Lovell|2006|p=15}} "barrier(s)" (}}, zhàng),{{sfn|Lovell|2006|p=15}} "the outer fortresses" {{nowrap|(}},}} wàibÇŽo),{{sfn|Waldron|1990|p=49}} and "the border wall(s)" {{nowrap|(t }},}} {{nowrap|s }},}} biānqiáng).{{sfn|Waldron|1983|p=651}} Poetic and informal names for the wall included "the Purple Frontier" {{nowrap|(}},}} Zǐsāi){{sfn|Waldron|1990|p=21}} and "the Earth Dragon" {{nowrap|(t }},}} {{nowrap|s }},}} TÇ”lóng).{{sfn|Waldron|1988|p=69}} Only during the Qing period did "Long Wall" become the catch-all term to refer to the many border walls regardless of their location or dynastic origin, equivalent to the English "Great Wall".{{sfn|Hessler|2007|p=59}}The current English name evolved from accounts of {{nowrap|"the Chinese wall"}} from early modern European travelers.{{sfn|Hessler|2007|p=59}} By the 19th century,{{sfn|Hessler|2007|p=59}} "The Great Wall of China" had become standard in English and French, although other European languages such as German continue to refer to it as "the Chinese wall."

{{further|Great Wall of Qi}}The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn period between the 8th and 5th centuries BC.WEB,weblink zh:歷代王朝修長城, Chiculture.net, October 24, 2010, zh, During this time and the subsequent Warring States period, the states of Qin, Wei, Zhao, Qi, Yan, and ZhongshanWEB,weblink zh:古代长城 – 战争与和平的纽带, Newsmth.net, October 24, 2010, zh, WEB,weblink zh:万里长城, Newsmth.net, October 24, 2010, zh, all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were made mostly by stamping earth and gravel between board frames.King Zheng of Qin conquered the last of his opponents and unified China as the First Emperor of the Qin dynasty ("Qin Shi Huang") in 221 BC. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the sections of the walls that divided his empire among the former states. To position the empire against the Xiongnu people from the north, however, he ordered the building of new walls to connect the remaining fortifications along the empire's northern frontier. "Build and move on" was a central guiding principle in constructing the wall, implying that the Chinese were not erecting a permanently fixed border.BOOK, Empires in World History: Power and the Politics of Difference, Burbank, Jane, Cooper, Frederick, Princeton University Press, 2010, Princeton, New Jersey, 45, Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today. The human cost of the construction is unknown, but it has been estimated by some authors that hundreds of thousands,{{sfn|Slavicek|Mitchell|Matray|2005|p=35}} if not up to a million, workers died building the Qin wall.{{sfn|Evans|2006|p=3}}WEB,weblink Defense and Cost of The Great Wall, 3, Paul and Bernice Noll's Window on the World, July 26, 2011, Later, the Han,WEB,weblink British researcher discovers piece of Great Wall 'marooned outside China', Coonan, Clifford, February 27, 2012, February 28, 2012, The Irish Times, the Sui, and the Northern dynasties all repaired, rebuilt, or expanded sections of the Great Wall at great cost to defend themselves against northern invaders.{{sfn|Waldron|1983|p=653}} The Tang and Song dynasties did not undertake any significant effort in the region.{{sfn|Waldron|1983|p=653}} The Liao, Jin, and Yuan dynasties, who ruled Northern China throughout most of the 10th–13th centuries, constructed defensive walls in the 12th century but those were located much to the north of the Great Wall as we know it, within China's province of Inner Mongolia and in Mongolia itself.{{sfnm|Waldron|1983|1p=654|Haw|2006|2pp=52–54}}

Ming era

File:GreatWallChina4.png|thumb|The extent of the Ming Empire and its walls]]The Great Wall concept was revived again under the Ming in the 14th century,{{sfn|Karnow|2008|p=192}} and following the Ming army's defeat by the Oirats in the Battle of Tumu. The Ming had failed to gain a clear upper hand over the Mongolian tribes after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the nomadic tribes out by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Yellow River.Unlike the earlier fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. Up to 25,000 watchtowers are estimated to have been constructed on the wall.{{sfn|Szabó|Dávid|Loczy|2010|p=220}} As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the walls. Sections near the Ming capital of Beijing were especially strong.{{sfn|Evans|2006|p=177}} Qi Jiguang between 1567 and 1570 also repaired and reinforced the wall, faced sections of the ram-earth wall with bricks and constructed 1,200 watchtowers from Shanhaiguan Pass to Changping to warn of approaching Mongol raiders.WEB, Great Wall at Mutianyu,weblink Great Wall of China, yes,weblink" title="web.archive.org/web/20130309091217weblink">weblink March 9, 2013, mdy-all, During the 1440s–1460s, the Ming also built a so-called "Liaodong Wall". Similar in function to the Great Wall (whose extension, in a sense, it was), but more basic in construction, the Liaodong Wall enclosed the agricultural heartland of the Liaodong province, protecting it against potential incursions by Jurched-Mongol Oriyanghan from the northwest and the Jianzhou Jurchens from the north. While stones and tiles were used in some parts of the Liaodong Wall, most of it was in fact simply an earth dike with moats on both sides.{{sfn|Edmonds|1985|pp=38–40}}Towards the end of the Ming, the Great Wall helped defend the empire against the Manchu invasions that began around 1600. Even after the loss of all of Liaodong, the Ming army held the heavily fortified Shanhai Pass, preventing the Manchus from conquering the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, after Beijing had already fallen to Li Zicheng's rebels. Before this time, the Manchus had crossed the Great Wall multiple times to raid, but this time it was for conquest. The gates at Shanhai Pass were opened on May 25 by the commanding Ming general, Wu Sangui, who formed an alliance with the Manchus, hoping to use the Manchus to expel the rebels from Beijing.{{sfn|Lovell|2006|p=254}} The Manchus quickly seized Beijing, and eventually defeated both the rebel-founded Shun dynasty and the remaining Ming resistance, establishing the Qing dynasty rule over all of China.{{sfn|Elliott|2001|pp=1–2}}Under Qing rule, China's borders extended beyond the walls and Mongolia was annexed into the empire, so constructions on the Great Wall were discontinued. On the other hand, the so-called Willow Palisade, following a line similar to that of the Ming Liaodong Wall, was constructed by the Qing rulers in Manchuria. Its purpose, however, was not defense but rather to prevent Han Chinese migration into Manchuria.Elliott, Mark C. "The Limits of Tartary: Manchuria in Imperial and National Geographies."

The Great Wall in 1907
None of the Europeans who visited Yuan China or Mongolia, such as Marco Polo, Giovanni da Pian del Carpine, William of Rubruck, Giovanni de' Marignolli and Odoric of Pordenone, mentioned the Great Wall.BOOK, Ruysbroek, Willem van,weblink The Journey of William of Rubruck to the Eastern Parts of the World, 1253–55, as Narrated by Himself, with Two Accounts of the Earlier Journey of John of Pian de Carpine, London, The Hakluyt Society, 1255, 1900, Translated from the Latin by William Woodville Rockhill, {{sfn|Haw|2006|pp=53–54}}The North African traveler Ibn Battuta, who also visited China during the Yuan dynasty ca. 1346, had heard about China's Great Wall, possibly before he had arrived in China.{{sfn|Haw|2006|pp=54–55}} He wrote that the wall is "sixty days' travel" from Zeitun (modern Quanzhou) in his travelogue Gift to Those Who Contemplate the Wonders of Cities and the Marvels of Travelling. He associated it with the legend of the wall mentioned in the Qur'an,Qur'an, XVIII: "The Cave". English translations hosted at (:s:Main Page|Wikisource) include (:s:The Holy Qur'an (Maulana Muhammad Ali)/18. The Cave|Maulana Muhammad Ali)'s, (:s:The Qur'an (Palmer)/Kahf|E.H. Palmer)'s, and the (:s:Quran (Progressive Muslims Organization)/18|Progressive Muslims Organization)'s. which Dhul-Qarnayn (commonly associated with Alexander the Great) was said to have erected to protect people near the land of the rising sun from the savages of Gog and Magog. However, Ibn Battuta could find no one who had either seen it or knew of anyone who had seen it, suggesting that although there were remnants of the wall at that time, they weren't significant.{{sfn|Haw|2006|pp=53–55}}Soon after Europeans reached Ming China by ship in the early 16th century, accounts of the Great Wall started to circulate in Europe, even though no European was to see it for another century. Possibly one of the earliest European descriptions of the wall and of its significance for the defense of the country against the "Tartars" (i.e. Mongols), may be the one contained in João de Barros's 1563 Asia.BOOK, Barros, João de, Ásia de João de Barros: Dos feitos que os portugueses fizeram no descobrimento dos mares e terras do Oriente, 3a Década, pp. 186–204 (originally Vol. II, Ch. vii), V, Lisbon, 1563, 1777,weblink Lisboa, Other early accounts in Western sources include those of Gaspar da Cruz, Bento de Goes, Matteo Ricci, and Bishop Juan González de Mendoza.{{sfn|Waldron|1990|pp=204–05}} In 1559, in his work "A Treatise of China and the Adjoyning Regions," Gaspar da Cruz offers an early discussion of the Great Wall.{{sfn|Waldron|1990|pp=204–05}} Perhaps the first recorded instance of a European actually entering China via the Great Wall came in 1605, when the Portuguese Jesuit brother Bento de Góis reached the northwestern Jiayu Pass from India.{{sfn|Yule|1866|p=579|ps=This section is the report of Góis's travel, as reported by Matteo Ricci in De Christiana expeditione apud Sinas (published 1615), annotated by Henry Yule).}} Early European accounts were mostly modest and empirical, closely mirroring contemporary Chinese understanding of the Wall,{{sfn|Waldron|1990|pp=2–4}} although later they slid into hyperbole,{{sfn|Waldron|1990|p=206}} including the erroneous but ubiquitous claim that the Ming Walls were the same ones that were built by the First Emperor in the 3rd century BC.{{sfn|Waldron|1990|p=206}}When China opened its borders to foreign merchants and visitors after its defeat in the First and Second Opium Wars, the Great Wall became a main attraction for tourists. The travelogues of the later 19th century further enhanced the reputation and the mythology of the Great Wall,{{sfn|Waldron|1990|p=209}} such that in the 20th century, a persistent misconception exists about the Great Wall of China being visible from the Moon or even Mars.{{sfn|Waldron|1990|p=214}}{{anchor|Inner Great Wall}}

The Great Wall at Mutianyu, near Beijing
(File:Great Wall of China in tourist season.jpg|thumb|Great Wall of China in tourist season)Before the use of bricks, the Great Wall was mainly built from rammed earth, stones, and wood. During the Ming, however, bricks were heavily used in many areas of the wall, as were materials such as tiles, lime, and stone. The size and weight of the bricks made them easier to work with than earth and stone, so construction quickened. Additionally, bricks could bear more weight and endure better than rammed earth. Stone can hold under its own weight better than brick, but is more difficult to use. Consequently, stones cut in rectangular shapes were used for the foundation, inner and outer (:wikt:brim|brims), and gateways of the wall. Battlements line the uppermost portion of the vast majority of the wall, with defensive gaps a little over {{convert|30|cm|abbr=on}} tall, and about {{convert|23|cm|abbr=on}} wide. From the parapets, guards could survey the surrounding land.{{sfn|Turnbull|2007|p=29}} Communication between the army units along the length of the Great Wall, including the ability to call reinforcements and warn garrisons of enemy movements, was of high importance. Signal towers were built upon hill tops or other high points along the wall for their visibility. Wooden gates could be used as a trap against those going through. Barracks, stables, and armories were built near the wall's inner surface.{{sfn|Turnbull|2007|p=29}}

Many western sections of the wall are Mudbrick, rather than brick and stone, and thus are more susceptible to erosion.CHINA'S WALL BECOMING LESS AND LESS GREAT DATE = AUGUST 29, 2007ACCESSDATE =AUGUST 30, 2007, In 2014 a portion of the wall near the border of Liaoning and Hebei province was repaired with concrete.

Visibility from space

From the Moon

One of the earliest known references to the myth that the Great Wall can be seen from the moon appears in a letter written in 1754 by the English antiquary William Stukeley. Stukeley wrote that, "This mighty wall {{bracket|Hadrian's wall}} of four score miles [130 km] in length is only exceeded by the Chinese Wall, which makes a considerable figure upon the terrestrial globe, and may be discerned at the Moon."The Family Memoirs of the Rev. William Stukeley (1887) Vol. 3, p. 142. (1754). The claim was also mentioned by Henry Norman in 1895 where he states "besides its age it enjoys the reputation of being the only work of human hands on the globe visible from the Moon."Norman, Henry, The Peoples and Politics of the Far East, p. 215. (1895). The issue of "canals" on Mars was prominent in the late 19th century and may have led to the belief that long, thin objects were visible from space. The claim that the Great Wall is visible from the moon also appears in 1932's Ripley's Believe It or Not! strip"The Great Wall of China, Ripley's Believe It or Not, 1932. and in Richard Halliburton's 1938 book Second Book of Marvels.The claim that the Great Wall is visible from the moon has been debunked many times,Urban Legends.com website. Accessed May 12, 2010."Can you see the Great Wall of China from the moon or outer space?", Answers.com. Accessed May 12, 2010.Cecil Adams, "Is the Great wall of China the only manmade object byou can see from space?", The Straight Dope. Accessed May 12, 2010.Snopes, "Great wall from space", last updated July 21, 2007. Accessed May 12, 2010."Is China's Great Wall Visible from Space?", Scientific American, February 21, 2008. "... the wall is only visible from low orbit under a specific set of weather and lighting conditions. And many other structures that are less spectacular from an earthly vantage point—desert roads, for example—appear more prominent from an orbital perspective." but is still ingrained in popular culture."Metro Tescos", The Times (London), April 26, 2010. Found at The Times website. Accessed May 12, 2010. The wall is a maximum {{convert|9.1|m|ftin|abbr=on}} wide, and is about the same color as the soil surrounding it. Based on the optics of resolving power (distance versus the width of the iris: a few millimeters for the human eye, meters for large telescopes) only an object of reasonable contrast to its surroundings which is {{convert|70|mi|order=flip|abbr=on}} or more in diameter (1 arc-minute) would be visible to the unaided eye from the Moon, whose average distance from Earth is {{convert|384393|km|abbr=on}}. The apparent width of the Great Wall from the Moon is the same as that of a human hair viewed from {{convert|3|km|abbr=on|0}} away. To see the wall from the Moon would require spatial resolution 17,000 times better than normal (20/20) vision.{{sfn|López-Gil|2008|pp=3–4}} Unsurprisingly, no lunar astronaut has ever claimed to have seen the Great Wall from the Moon.

From low Earth orbit

(File:Great Wall of China, Satellite image.jpeg|thumb|A satellite image of a section of the Great Wall in northern Shanxi, running diagonally from lower left to upper right and not to be confused with the more prominent river running from upper left to lower right. The region pictured is {{convert|12|x|12|km|abbr=on|0}}.)A more controversial question is whether the Wall is visible from low Earth orbit (an altitude of as little as {{convert|100|mi|km|-1|order=flip|abbr=on}}). NASA claims that it is barely visible, and only under nearly perfect conditions; it is no more conspicuous than many other man-made objects.WEB,weblink NASA – Great Wall of China, Nasa.gov, July 31, 2010, Other authors have argued that due to limitations of the optics of the eye and the spacing of photoreceptors on the retina, it is impossible to see the wall with the naked eye, even from low orbit, and would require visual acuity of 20/3 (7.7 times better than normal).{{sfn|López-Gil|2008|pp=3–4}}Astronaut William Pogue thought he had seen it from Skylab but discovered he was actually looking at the Grand Canal of China near Beijing. He spotted the Great Wall with binoculars, but said that "it wasn't visible to the unaided eye." U.S. Senator Jake Garn claimed to be able to see the Great Wall with the naked eye from a space shuttle orbit in the early 1980s, but his claim has been disputed by several U.S. astronauts. Veteran U.S. astronaut Gene Cernan has stated: "At Earth orbit of {{convert|100|to|200|mi|km|-1|disp=sqbr}} 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."In 2001, Neil Armstrong stated about the view from Apollo 11: "I do not believe that, at least with my eyes, there would be any man-made object that I could see. I have not yet found somebody who has told me they've seen the Wall of China from Earth orbit. ... I've asked various people, particularly Shuttle guys, that have been many orbits around China in the daytime, and the ones I've talked to didn't see it."WEB,weblink PDF, July 31, 2010, Stephen E. Ambrose, Dr. Stephen E. Ambrose, Douglas Brinkley, Dr. Douglas Brinkley, September 19, 2001, NASA, Johnson Space Center Oral History Project Oral History Transcript – Neil Armstrong, In October 2003, Chinese astronaut Yang Liwei stated that he had not been able to see the Great Wall of China. In response, the European Space Agency (ESA) issued a press release reporting that from an orbit between {{convert|160|and|320|km|mi|abbr=on|-1}}, the Great Wall is visible to the naked eye. In an attempt to further clarify things, the ESA published a picture of a part of the "Great Wall" photographed from low orbit. However, in a press release a week later, they acknowledged that the "Great Wall" in the picture was actually a river.{{sfn|López-Gil|2008|pp=3–4}}Leroy Chiao, a Chinese-American astronaut, took a photograph from the International Space Station that shows the wall. It was so indistinct that the photographer was not certain he had actually captured it. Based on the photograph, the China Daily later reported that the Great Wall can be seen from 'space' with the naked eye, under favorable viewing conditions, if one knows exactly where to look.Markus, Francis. (April 19, 2005). Great Wall visible in space photo. BBC News, Asia-Pacific section. Retrieved March 17, 2007. However, the resolution of a camera can be much higher than the human visual system, and the optics much better, rendering photographic evidence irrelevant to the issue of whether it is visible to the naked eye.{{sfn|López-Gil|2008|pp=3–4}}
