Chinese city wall
From Wikipedia, the free encyclopedia
Chinese city walls (Chinese: 城墙; pinyin: chéngqiáng; literally "city wall") refer to civic defensive systems used to protect towns and cities in China in pre-modern times. The system consists of walls, towers, and gates, which are often built to a uniform standard throughout the empire.

[edit] Meaning of the word Chengqiang
The Chinese word Chéngqiáng (城墙) can be used in two senses in the modern Chinese language. In a broad sense, it means all defensive walls, including the Great Wall of China, as well as similar structures in other countries such as Hadrian's Wall. In a narrow sense, Chengqiang specifically refers to defensive walls built around a city or town.
In classical Chinese, the character Chéng (城) denoted the defensive wall of the "inner city", housing government buildings. The character Guó (郭) denoted the defensive wall of the "outer city", housing mainly residences. The phrase Cháangchéng (长城), literally "the Long Wall", specifically referred to the Great Wall.
[edit] History
Like various other innovations in Chinese history, the invention of the city wall is attributed to a semi-mythological sage; in this case, to Xia Dynasty leader Gun (鲧), the father of Yu the Great<ref> Spring and Autumn of Wu and Yue (吴越春秋). Nanjing: Jiangsu Ancient Books Press. 1986</ref>. It is said that Gun built the inner wall (城) to defend the prince, and the outer wall (郭) to settle the people. An alternative theory attributes the first city wall to Huangdi<ref> "Biography of Xuanyuan" (轩辕本纪). in Sima Qian. Shiji. Beijing: Zhonghua Publishing. 2005. ISBN 7-10100-304-4</ref>. A number of neolithic-period walls surrounding substantial settlements have been excavated in recent years. These include a stone wall at Sanxingdui, and several tamped earth walls at the Longshan culture site. These walls generally protected settlements the size of a large village.
Most towns of a significant size possessed a city wall from the Zhou Dynasty onwards. For example, the city wall of Pingyao were first constructed between 827 BC and 782 BC, in the reign of King Xuan of Zhou. The city wall of Suzhou followed, prior to their demolition in the 1960s and 1970s, largely the same plan as set down by Wu Zixu in the 5th century BC. By the Yuan Dynasty, it was government policy that towns which were administrative seats of county-level units or above were to have defensive walls.
The construction of city walls grew to a peak in the Ming Dynasty and Qing Dynasty. Sophisticated construction techniques meant that major city walls, such as that in the capitals Beijing and Nanjing, were specifically built to withstand cannonfire. However, with the advent of modern Western firearms, traditional fortifications began to lose their defensive functions in the 19th and 20th centuries. The traditional city wall also proved an obstacle to efficient trade and intercourse. For example, the city wall of Shanghai, built to repel Wokou raiders in the Ming dynasty, was almost completely demolished after the Xinhai Revolution at the request of the city's merchant community.
After the founding of the People's Republic of China, a political dimension was added to the economic problem posed by city walls. In Beijing, for example, the proposed demolition of the city walls was at first opposed by experts ranging from architect Liang Sicheng, to Soviet advisor Mosin, on the grounds that the city walls of Beijing were the most sophisticated and well-preserved system of city walls in China. However, in 1958 Mao Zedong intervened, and declared that the demolition of the old city wall was a political issue. Despite mayor Peng Zhen's efforts to preserve gates and towers, by 1970 almost all of the city wall had been demolished.
[edit] Composition
Chinese city walls are distinguished from European walled cities and castles in several respects. Because many Chinese cities were deliberately sited and planned, city walls tend to be rectangular or square, instead of being constrained by geography in the case of many walled cities in the West. Philosophical and even feng shui considerations were adopted in siting gates and towers, and the walled city itself.
In contrast to defensive systems in mediaeval Europe that typically centre on a castle, this is rarely the case in Chinese cities. Instead, the city's administrative centre is spread over a relatively large area, which may or may not be surrounded by a second set of "inner" walls similar in shape and construction to the main, outer wall.
Long-term strategic considerations adopted in the planning process also meant that the walls of important cities often enclosed an area much larger than the existing urban areas, both in order to ensure excess capacity for growth, and to secure resources such as timber and farmland in times of war. Thus, for example, the city wall of Quanzhou in Fujian still contained one quarter vacant land by 1945. The city wall of Suzhou by the Republic of China era still contained large tracts of farmland<ref>Chen Zhengxiang (陈正祥).

The City Wall of Nanjing, built in the Ming Dynasty, enclosed an area large enough to house an airport, bamboo forests, and lakes in modern times<ref> Ray Huang. China: a Macro History.

Several features are typical of most Chinese city walls.
[edit] Shape
Where allowed by geography, Chinese city walls are rectangular in shape, with four orthogonal walls. Some wall systems are composed of a number of such rectangles, set adjacent to or concentrically within each other. For example, the city wall of Beijing is composed of four rectangles: a wider outer city to the south, a narrower inner city to the north, an imperial city within the inner city, and the Forbidden City at the centre of that.
The walls can be constructed of a variety of materials. Common materials include rammed earth, compressed earth blocks, brick, stone, and any combination of these. In its standardised form during the Ming and Qing dynasties, the wall is composed of a core made of compressed earth and mixed debris, strengthened by various binders. The wall is then surfaced with bricks. It is topped with crenellations facing out, and a parapet facing in.
[edit] Gates and towers
Gates are placed symmetrically along the walls. The principal gate was traditionally located at the centre of the south wall. Gatehouses are generally built of wood and brick, which sit atop a raised and expanded section of the wall, surrounded by crenellated battlements. A tunnel runs under the gatehouse, with several metal grates and wooden doors. Camouflaged defensive positions are placed along the tunnel (in an effect similar to murder holes). An "archery tower" is often placed in front of the main gatehouse, forming a barbican. In large gates there may be multiple barbicans - the main gate of Nanjing had three. Gatehouses are accessed by ramps, called horse ramps (马道), which sit against the wall adjacent to the gate.
Towers that protrude from the wall are located at regular intervals along the wall. Large and elaborate towers, called corner towers (角楼), are placed where two walls join (i.e. at corners). These are significantly higher than the wall itself, and give defenders a bird's eye view over both the city and its surroundings.
[edit] Moat
In larger cities, a moat surrounds the wall. This can be connected to canals or rivers both in the city and outside, thus providing both a defense and a convenient transportation route. Nearby waterways may be adopted or altered to connect to, or form part of, the moat.
