Great Wall of China

The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. Several walls were being built as early as the 7th century BCE; these, later joined together and made bigger and stronger, are now collectively referred to as the Great Wall. Especially famous is the wall built 220–206 BCE by Qin Shi Huang, the first Emperor of China. Little of that wall remains. Since then, the Great Wall has on and off been rebuilt, maintained, and enhanced; the majority of the existing wall is from the Ming Dynasty.

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.

Mutianyu (Chinese: 慕田峪; pinyin: Mùtiányù) is a section of the Great Wall of China located in Huairou County 70 km northeast of central Beijing. The Mutianyu section of the Great Wall is connected with Jiankou in the west and Lianhuachi in the east. As one of the best-preserved parts of the Great Wall, the Mutianyu section of the Great Wall used to serve as the northern barrier defending the capital and the imperial tombs.

First built in the mid-6th century during the Northern Qi, Mutianyu Great Wall is older than the Badaling section of the Great Wall. In the Ming dynasty, under the supervision of General Xu Da, construction of the present wall began on the foundation of the wall of Northern Qi. In 1404, a pass was built in the wall. In 1569, the Mutianyu Great Wall was rebuilt and till today most parts of it are well preserved. The Mutianyu Great Wall has the largest construction scale and best quality among all sections of Great Wall.

Wall

A wall is a structure that defines an area, carries a load, or provides shelter or security. There are many kinds of walls:

Etymology

Wall comes from Latin vallum meaning "...an earthen wall or rampart set with palisades, a row or line of stakes, a wall, a rampart, fortification..." while the Latin word murus means a defensive stone wallEnglish uses the same word to mean an external wall and the internal sides of a room, but this is not universal. Many languages distinguish between the two. In German, some of this distinction can be seen between Wand and Mauer, in Spanish between pared and muro.

Defensive wall

The word wall originally referred to defensive walls and ramparts.

China

China, officially the People's Republic of China (PRC), is a sovereign state in East Asia. It is the world's most populous country, with a population of over 1.35 billion. The PRC is a one-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces; five autonomous regions; four direct-controlled municipalities (Beijing, Tianjin, Shanghai and Chongqing); two mostly self-governing special administrative regions (Hong Kong and Macau); and claims sovereignty over Taiwan.

Covering approximately 9.6 million square kilometers, China is the world's second-largest country by land area, and either the third or fourth-largest by total area, depending on the method of measurement. China's landscape is vast and diverse, ranging from forest steppes and the Gobi and Taklamakan deserts in the arid north to subtropical forests in the wetter south. The Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, run from the Tibetan Plateau to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long, and is bounded by the Bohai, Yellow, East and South China Seas.
