The Forbidden City (Chinese: 紫禁城; pinyin: Zǐjìnchéng) is a palace complex in central Beijing, China. It houses the Palace Museum, and was the former Chinese imperial palace and state residence of the Emperor of China from the Ming dynasty (since the Yongle Emperor) to the end of the Qing dynasty, between 1420 and 1924. The Forbidden City served as the home of Chinese emperors and their households and was the ceremonial and political center of the Chinese government for almost 500 years.
Constructed from 1406 to 1420, the complex consists of 980 buildings and covers 72 hectares (over 180 acres). The palace exemplifies traditional Chinese palatial architecture, and has influenced cultural and architectural developments in East Asia and elsewhere. The Forbidden City was declared a World Heritage Site in 1987, and is listed by UNESCO as the largest collection of preserved ancient wooden structures in the world.
Since 1925, the Forbidden City has been under the charge of the Palace Museum, whose extensive collection of artwork and artifacts were built upon the imperial collections of the Ming and Qing dynasties. Part of the museum's former collection is now in the National Palace Museum in Taipei. Both museums descend from the same institution but were split after the Chinese Civil War. Since 2012, the Forbidden City has seen an average of 14 million visitors annually, and received more than 19 million visitors in 2019.
The common English name "Forbidden City" is a translation of the Chinese name Zijin Cheng (Chinese: 紫禁城; pinyin: Zǐjìnchéng; lit.: 'Purple Forbidden City'). The name Zijin Cheng first formally appeared in 1576. Another English name of similar origin is "Forbidden Palace".
The name "Zijin Cheng" is a name with significance on many levels. Zi, or "Purple", refers to the North Star, which in ancient China was called the Ziwei Star, and in traditional Chinese astrology was the heavenly abode of the Celestial Emperor. The surrounding celestial region, the Ziwei Enclosure (Chinese: 紫微垣; pinyin: Zǐwēiyuán), was the realm of the Celestial Emperor and his family. The Forbidden City, as the residence of the terrestrial emperor, was its earthly counterpart. Jin, or "Forbidden", referred to the fact that no one could enter or leave the palace without the emperor's permission. Cheng means a city. Today, the site is most commonly known in Chinese as Gùgōng (故宫), which means the "Former Palace". The museum which is based in these buildings is known as the "Palace Museum" (Chinese: 故宫博物院; pinyin: Gùgōng Bówùyùan).
In Ming and Qing, the Forbidden City was also known as Da Nei (大内) or "Palace City" (宫城).
Construction lasted 14 years and required more than a million workers. Material used include whole logs of precious Phoebe zhennan wood (Chinese: 楠木; pinyin: nánmù) found in the jungles of south-western China, and large blocks of marble from quarries near Beijing. The floors of major halls were paved with "golden bricks" (Chinese: 金磚; pinyin: jīnzhuān), specially baked paving bricks from Suzhou.
From 1420 to 1644, the Forbidden City was the seat of the Ming dynasty. In April 1644, it was captured by rebel forces led by Li Zicheng, who proclaimed himself emperor of the Shun dynasty. He soon fled before the combined armies of former Ming general Wu Sangui and Manchu forces, setting fire to parts of the Forbidden City in the process.
By October, the Manchus had achieved supremacy in northern China, and a ceremony was held at the Forbidden City to proclaim the young Shunzhi Emperor as ruler of all China under the Qing dynasty. The Qing rulers changed the names on some of the principal buildings, to emphasise "Harmony" rather than "Supremacy", made the name plates bilingual (Chinese and Manchu), and introduced Shamanist elements to the palace.
In 1860, during the Second Opium War, Anglo-French forces took control of the Forbidden City and occupied it until the end of the war. In 1900 Empress Dowager Cixi fled from the Forbidden City during the Boxer Rebellion, leaving it to be occupied by forces of the treaty powers until the following year.
After being the home of 24 emperors – 14 of the Ming dynasty and 10 of the Qing dynasty – the Forbidden City ceased being the political centre of China in 1912 with the abdication of Puyi, the last Emperor of China. Under an agreement with the new Republic of China government, Puyi remained in the Inner Court, while the Outer Court was given over to public use, until he was evicted after a coup in 1924. The Palace Museum was then established in the Forbidden City in 1925. In 1933, the Japanese invasion of China forced the evacuation of the national treasures in the Forbidden City. Part of the collection was returned at the end of World War II, but the other part was evacuated to Taiwan in 1948 under orders of Chiang Kai-shek, whose Kuomintang was losing the Chinese Civil War. This relatively small but high quality collection was kept in storage until 1965, when it again became public, as the core of the National Palace Museum in Taipei.
After the establishment of the People's Republic of China in 1949, some damage was done to the Forbidden City as the country was swept up in revolutionary zeal. During the Cultural Revolution, however, further destruction was prevented when Premier Zhou Enlai sent an army battalion to guard the city.
The Forbidden City was declared a World Heritage Site in 1987 by UNESCO as the "Imperial Palace of the Ming and Qing Dynasties", due to its significant place in the development of Chinese architecture and culture. It is currently administered by the Palace Museum, which is carrying out a sixteen-year restoration project to repair and restore all buildings in the Forbidden City to their pre-1912 state.
The Forbidden City is a rectangle, measuring 961 metres (3,153 ft) from north to south and 753 metres (2,470 ft) from east to west. It consists of 980 surviving buildings with 8,886 bays of rooms. A common myth states that there are 9,999 rooms including antechambers, based on oral tradition, and it is not supported by survey evidence. The Forbidden City was designed to be the centre of the ancient, walled city of Beijing. It is enclosed in a larger, walled area called the Imperial City. The Imperial City is, in turn, enclosed by the Inner City; to its south lies the Outer City.
The Forbidden City remains important in the civic scheme of Beijing. The central north–south axis remains the central axis of Beijing. This axis extends to the south through Tiananmen gate to Tiananmen Square, the ceremonial centre of the People's Republic of China, and on to Yongdingmen. To the north, it extends through Jingshan Hill to the Bell and Drum Towers. This axis is not exactly aligned north–south, but is tilted by slightly more than two degrees. Researchers now believe that the axis was designed in the Yuan dynasty to be aligned with Xanadu, the other capital of their empire.
Walls and gates
The Forbidden City is surrounded by a 7.9 metres (26 ft) high city wall and a 6 metres (20 ft) deep by 52 metres (171 ft) wide moat. The walls are 8.62 metres (28.3 ft) wide at the base, tapering to 6.66 metres (21.9 ft) at the top. These walls served as both defensive walls and retaining walls for the palace. They were constructed with a rammed earth core, and surfaced with three layers of specially baked bricks on both sides, with the interstices filled with mortar.
At the four corners of the wall sit towers (E) with intricate roofs boasting 72 ridges, reproducing the Pavilion of Prince Teng and the Yellow Crane Pavilion as they appeared in Song dynasty paintings. These towers are the most visible parts of the palace to commoners outside the walls, and much folklore is attached to them. According to one legend, artisans could not put a corner tower back together after it was dismantled for renovations in the early Qing dynasty, and it was only rebuilt after the intervention of carpenter-immortal Lu Ban.
The wall is pierced by a gate on each side. At the southern end is the main Meridian Gate (A). To the north is the Gate of Divine Might (B), which faces Jingshan Park. The east and west gates are called the "East Glorious Gate" (D) and "West Glorious Gate" (C). All gates in the Forbidden City are decorated with a nine-by-nine array of golden door nails, except for the East Glorious Gate, which has only eight rows.
The Meridian Gate has two protruding wings forming three sides of a square (Wumen, or Meridian Gate, Square) before it. The gate has five gateways. The central gateway is part of the Imperial Way, a stone flagged path that forms the central axis of the Forbidden City and the ancient city of Beijing itself, and leads all the way from the Gate of China in the south to Jingshan in the north. Only the Emperor may walk or ride on the Imperial Way, except for the Empress on the occasion of her wedding, and successful students after the Imperial Examination.
Outer Court or the Southern Section
Traditionally, the Forbidden City is divided into two parts. The Outer Court (外朝) or Front Court (前朝) includes the southern sections, and was used for ceremonial purposes. The Inner Court (内廷) or Back Palace (后宫) includes the northern sections, and was the residence of the Emperor and his family, and was used for day-to-day affairs of state. (The approximate dividing line shown as red dash in the plan above.) Generally, the Forbidden City has three vertical axes. The most important buildings are situated on the central north–south axis.
Entering from the Meridian Gate, one encounters a large square, pierced by the meandering Inner Golden Water River, which is crossed by five bridges. Beyond the square stands the Gate of Supreme Harmony (F). Behind that is the Hall of Supreme Harmony Square. A three-tiered white marble terrace rises from this square. Three halls stand on top of this terrace, the focus of the palace complex. From the south, these are the Hall of Supreme Harmony (太和殿), the Hall of Central Harmony (中和殿), and the Hall of Preserving Harmony (保和殿).
The Hall of Supreme Harmony (G) is the largest, and rises some 30 metres (98 ft) above the level of the surrounding square. It is the ceremonial centre of imperial power, and the largest surviving wooden structure in China. It is nine bays wide and five bays deep, the numbers 9 and 5 being symbolically connected to the majesty of the Emperor. Set into the ceiling at the centre of the hall is an intricate caisson decorated with a coiled dragon, from the mouth of which issues a chandelier-like set of metal balls, called the "Xuanyuan Mirror". In the Ming dynasty, the Emperor held court here to discuss affairs of state. During the Qing dynasty, as Emperors held court far more frequently, a less ceremonious location was used instead, and the Hall of Supreme Harmony was only used for ceremonial purposes, such as coronations, investitures, and imperial weddings.
The Hall of Central Harmony is a smaller, square hall, used by the Emperor to prepare and rest before and during ceremonies. Behind it, the Hall of Preserving Harmony, was used for rehearsing ceremonies, and was also the site of the final stage of the Imperial examination. All three halls feature imperial thrones, the largest and most elaborate one being that in the Hall of Supreme Harmony.
At the centre of the ramps leading up to the terraces from the northern and southern sides are ceremonial ramps, part of the Imperial Way, featuring elaborate and symbolic bas-relief carvings. The northern ramp, behind the Hall of Preserving Harmony, is carved from a single piece of stone 16.57 metres (54.4 ft) long, 3.07 metres (10.1 ft) wide, and 1.7 metres (5.6 ft) thick. It weighs some 200 tonnes and is the largest such carving in China. The southern ramp, in front of the Hall of Supreme Harmony, is even longer, but is made from two stone slabs joined together – the joint was ingeniously hidden using overlapping bas-relief carvings, and was only discovered when weathering widened the gap in the 20th century.
In the south west and south east of the Outer Court are the halls of Military Eminence (H) and Literary Glory (J). The former was used at various times for the Emperor to receive ministers and hold court, and later housed the Palace's own printing house. The latter was used for ceremonial lectures by highly regarded Confucian scholars, and later became the office of the Grand Secretariat. A copy of the Siku Quanshu was stored there. To the north-east are the Southern Three Places (南三所) (K), which was the residence of the Crown Prince.
Inner Court or the Northern Section
The Inner Court is separated from the Outer Court by an oblong courtyard lying orthogonal to the City's main axis. It was the home of the Emperor and his family. In the Qing dynasty, the Emperor lived and worked almost exclusively in the Inner Court, with the Outer Court used only for ceremonial purposes.
Back Three Palaces
At the centre of the Inner Court is another set of three halls (L). From the south, these are:
Smaller than the Outer Court halls, the three halls of the Inner Court were the official residences of the Emperor and the Empress. The Emperor, representing Yang and the Heavens, would occupy the Palace of Heavenly Purity. The Empress, representing Yin and the Earth, would occupy the Palace of Earthly Tranquility. In between them was the Hall of Union, where the Yin and Yang mixed to produce harmony.
The Palace of Heavenly Purity is a double-eaved building, and set on a single-level white marble platform. It is connected to the Gate of Heavenly Purity to its south by a raised walkway. In the Ming dynasty, it was the residence of the Emperor. However, beginning from the Yongzheng Emperor of the Qing dynasty, the Emperor lived instead at the smaller Hall of Mental Cultivation (N) to the west, out of respect to the memory of the Kangxi Emperor. The Palace of Heavenly Purity then became the Emperor's audience hall. A caisson is set into the roof, featuring a coiled dragon. Above the throne hangs a tablet reading "Justice and Honour" (Chinese: 正大光明; pinyin: zhèngdàguāngmíng).
The Palace of Earthly Tranquility (坤寧宮) is a double-eaved building, 9 bays wide and 3 bays deep. In the Ming dynasty, it was the residence of the Empress. In the Qing dynasty, large portions of the Palace were converted for Shamanist worship by the new Manchu rulers. From the reign of the Yongzheng Emperor, the Empress moved out of the Palace. However, two rooms in the Palace of Earthly Harmony were retained for use on the Emperor's wedding night.
Behind these three halls lies the Imperial Garden (M). Relatively small, and compact in design, the garden nevertheless contains several elaborate landscaping features. To the north of the garden is the Gate of Divine Might.
Directly to the west is the Hall of Mental Cultivation (N). Originally a minor palace, this became the de facto residence and office of the Emperor starting from Yongzheng. In the last decades of the Qing dynasty, empresses dowager, including Cixi, held court from the eastern partition of the hall. Located around the Hall of Mental Cultivation are the offices of the Grand Council and other key government bodies.
The north-eastern section of the Inner Court is taken up by the Palace of Tranquil Longevity (寧壽宮) (O), a complex built by the Qianlong Emperor in anticipation of his retirement. It mirrors the set-up of the Forbidden City proper and features an "outer court", an "inner court", and gardens and temples. The entrance to the Palace of Tranquil Longevity is marked by a glazed-tile Nine Dragons Screen. This section of the Forbidden City is being restored in a partnership between the Palace Museum and the World Monuments Fund, a long-term project expected to finish in 2017.
Six Western and Six Eastern Palaces
To the west and to the east of the three main halls of the Inner Court are the Western Palaces (Xiliugong) and the Eastern Palaces (Dongliugong). These palaces were the residences of the imperial consorts. Six Palaces lay to the West and six to the East of the three main halls, hence the name. The architecture of the 12 Palaces, connected by passageways, is more or less the same. The Western and Eastern Palaces each have a layout of three palaces on either side of an alley that runs from north to south. Every Palace has its own courtyards, main halls, and side-halls. The main halls stand in the middle and the side-halls are in the east and west. The front courtyard and its main hall was used for receptions, while the back courtyard and its main hall served as living quarters.
A consort with the rank of Concubine and above was given a residence in the main sections of a Palace and was the manager of that Palace, an honor in itself. Lower ranking consorts (Noble Ladies and below) lived in the side-hall of the Palaces and were supervised by the higher ranking consort. The 12 Palaces were the place where many of the Qing emperors were born and grew up, and they formed the daily life of the imperial family. During the late Qing era, Empress Dowager Cixi resided in one of the Western Palaces and became known as the "Western empress". Her co-regent Empress Dowager Ci'an lived in one of the Eastern Palaces and was thus known as the “Eastern empress”.
The name of the Palaces were:
Western Six Palaces
- Palace of Eternal Longevity (永寿宫)
- Hall of the Supreme Principle (太极殿)
- Palace of Eternal Spring (长春宫)
- Palace of Earthly Honour (翊坤宫)
- Palace of Gathering Elegance (储秀宫)
- Palace of Universal Happiness (咸福宫)
- Palace of Benevolence and Tranquility (慈宁宮 )
Eastern Six Palaces
- Palace of Great Benevolence (景仁宫)
- Palace of Heavenly Grace (承乾宫)
- Palace of Accumulated Purity (锺粹宫)
- Palace of Prolonged Happiness (延禧宫)
- Palace of Great Brilliance (景阳宫)
- Palace of Eternal Harmony (永和宫)
Cining Palace and Shoukang Palace
To the west of the Hall of Mental Cultivation (N) in the western area of the Inner Court is Cining Palace (Palace of Compassion and Tranquility) and Shoukang Palace (Palace of Longevity and Good Health). The palaces were the residences of widowed consorts of previous emperors. In accordance with feudal manners, emperors should not live with the wives of late emperors, so they lived in this separate area of the Inner Court. The Cining palace is bigger and older than Shoukang Palace which is located to the west of Cining Palace. To the south of Cining Palace is Cining garden.
Religion was an important part of life for the imperial court. In the Qing dynasty, the Palace of Earthly Harmony became a place of Manchu Shamanist ceremony. At the same time, the native Chinese Taoist religion continued to have an important role throughout the Ming and Qing dynasties. There were two Taoist shrines, one in the imperial garden and another in the central area of the Inner Court.
Another prevalent form of religion in the Qing dynasty palace was Buddhism. A number of temples and shrines were scattered throughout the Inner Court, including that of Tibetan Buddhism or Lamaism. Buddhist iconography also proliferated in the interior decorations of many buildings. Of these, the Pavilion of the Rain of Flowers is one of the most important. It housed a large number of Buddhist statues, icons, and mandalas, placed in ritualistic arrangements.
The Forbidden City is surrounded on three sides by imperial gardens. To the north is Jingshan Park, also known as Prospect Hill, an artificial hill created from the soil excavated to build the moat and from nearby lakes.
To the west lies Zhongnanhai, a former royal garden centred on two connected lakes, which now serves as the central headquarters for the Communist Party of China and the State Council of the People's Republic of China. To the north-west lies Beihai Park, also centred on a lake connected to the southern two, and a popular royal park.
To the south of the Forbidden City were two important shrines – the Imperial Shrine of Family or the Imperial Ancestral Temple (Chinese: 太廟; pinyin: Tàimiào) and the Imperial Shrine of State or Beijing Shejitan (Chinese: 社稷壇; pinyin: Shèjìtán), where the Emperor would venerate the spirits of his ancestors and the spirit of the nation, respectively. Today, these are the Beijing Labouring People's Cultural Hall and Zhongshan Park (commemorating Sun Yat-sen) respectively.
To the south, two nearly identical gatehouses stand along the main axis. They are the Upright Gate (Chinese: 端门; pinyin: Duānmén) and the more famous Tiananmen Gate, which is decorated with a portrait of Mao Zedong in the centre and two placards to the left and right: "Long Live the People's Republic of China" (Chinese: 中华人民共和国万岁; pinyin: zhōnghuárénmíngònghéguówànsuì) and "Long live the Great Unity of the World's Peoples" (Chinese: 世界人民大团结万岁; pinyin: shìjièrénmíndàtuánjiéwànsuì). The Tiananmen Gate connects the Forbidden City precinct with the modern, symbolic centre of the Chinese state, Tiananmen Square.
While development is now tightly controlled in the vicinity of the Forbidden City, throughout the past century uncontrolled and sometimes politically motivated demolition and reconstruction has changed the character of the areas surrounding the Forbidden City. Since 2000, the Beijing municipal government has worked to evict governmental and military institutions occupying some historical buildings, and has established a park around the remaining parts of the Imperial City wall. In 2004, an ordinance relating to building height and planning restriction was renewed to establish the Imperial City area and the northern city area as a buffer zone for the Forbidden City. In 2005, the Imperial City and Beihai (as an extension item to the Summer Palace) were included in the shortlist for the next World Heritage Site in Beijing.
The design of the Forbidden City, from its overall layout to the smallest detail, was meticulously planned to reflect philosophical and religious principles, and above all to symbolize the majesty of Imperial power. Some noted examples of symbolic designs include:
- Yellow is the color of the Emperor. Thus almost all roofs in the Forbidden City bear yellow glazed tiles. There are only two exceptions. The library at the Pavilion of Literary Profundity (文渊阁) had black tiles because black was associated with water, and thus fire-prevention. Similarly, the Crown Prince's residences have green tiles because green was associated with wood, and thus growth.
- The main halls of the Outer and Inner courts are all arranged in groups of three – the shape of the Qian triagram, representing Heaven. The residences of the Inner Court on the other hand are arranged in groups of six – the shape of the Kun triagram, representing the Earth.
- The sloping ridges of building roofs are decorated with a line of statuettes led by a man riding a phoenix and followed by an imperial dragon. The number of statuettes represents the status of the building – a minor building might have 3 or 5. The Hall of Supreme Harmony has 10, the only building in the country to be permitted this in Imperial times. As a result, its 10th statuette, called a "Hangshi", or "ranked tenth" (Chinese: 行十; pinyin: Hángshí), is also unique in the Forbidden City.
- The layout of buildings follows ancient customs laid down in the Classic of Rites. Thus, ancestral temples are in front of the palace. Storage areas are placed in the front part of the palace complex, and residences in the back.
The collections of the Palace Museum are based on the Qing imperial collection, including paintings, ceramics, seals, steles, sculptures, inscribed wares, bronze wares, enamel objects, etc. According to latest audit, it has 1,862,690 pieces of art. In addition, the imperial libraries housed a large collection of rare books and historical documents, including government documents of the Ming and Qing dynasties, which has since been transferred to the First Historical Archives.
From 1933, the threat of Japanese invasion forced the evacuation of the most important parts of the Museum's collection. After the end of World War II, this collection was returned to Nanjing. However, with the Communists' victory imminent in the Chinese Civil War, the Nationalist government decided to ship the pick of this collection to Taiwan. Of the 13,491 boxes of evacuated artefacts, 2,972 boxes are now housed in the National Palace Museum in Taipei. More than 8,000 boxes were returned to Beijing, but 2,221 boxes remain today in storage under the charge of the Nanjing Museum.
The Palace Museum holds 340,000 pieces of ceramics and porcelain. These include imperial collections from the Tang dynasty and the Song dynasty. It has close to 50,000 paintings, within which more than 400 date from before the Yuan dynasty (1271–1368), which is the largest in China. Its bronze collection dates from the early Shang dynasty. Of the almost 10,000 pieces held, about 1,600 are inscribed items from the pre-Qin period (to 221 BC). A significant part of the collection is ceremonial bronzeware from the imperial court. The Palace Museum has one of the largest collections of mechanical timepieces of the 18th and 19th centuries in the world, with more than 1,000 pieces. The collection contains both Chinese- and foreign-made pieces. Chinese pieces came from the palace's own workshops. Foreign pieces came from countries including Britain, France, Switzerland, the United States and Japan. Of these, the largest portion come from Britain.Jade has a unique place in Chinese culture. The Museum's collection includes some 30,000 pieces. The pre-Yuan dynasty part of the collection includes several pieces famed throughout history. The earliest pieces date from the Neolithic period. In addition to works of art, a large proportion of the Museum's collection consists of the artifacts of the imperial court. This includes items used by the imperial family and the palace in daily life. This comprehensive collection preserves the daily life and ceremonial protocols of the imperial era.
The Forbidden City, the culmination of the two-thousand-year development of classical Chinese and East Asian architecture, has been influential in the subsequent development of Chinese architecture, as well as providing inspiration for many artistic works.
- Depiction in art, film, literature and popular culture
The Forbidden City has served as the scene to many works of fiction. In recent years, it has been depicted in films and television series. Some notable examples include:
- The Forbidden City (1918), a fiction film about a Chinese emperor and an American.
- The Last Emperor (1987), a biographical film about Puyi, was the first feature film ever authorised by the government of the People's Republic of China to be filmed in the Forbidden City.
- Forbidden City Cop (1996) a Hong Kong wuxia comedy film about an imperial secret agent
- Marco Polo a joint NBC and RAI TV miniseries broadcast in the early 1980s, was filmed inside the Forbidden City. Note, however, that the present Forbidden City did not exist in the Yuan dynasty, when Marco Polo met Kublai Khan.
- The 2003 real-time strategy game Rise of Nations depicts the Forbidden City as one of the great wonders of the world; in terms of game mechanics, it functions identically to a major city and provides additional resources to the player.
- The Forbidden City is a buildable Wonder in many different titles of the Civilization series of video games.
