Beijing occupies 16,410 square kilometers in northern China at the northern tip of the North China Plain, bordered by Hebei Province on all sides except for a small southeastern section adjacent to Tianjin. The city sits at approximately 39.9 degrees north latitude and 116.4 degrees east longitude, placing it roughly level with Philadelphia and somewhat west of Tokyo in terms of global position. Seven ring roads encircle the urban core in concentric patterns, with the innermost Second Ring Road tracing the former path of the Ming Dynasty city walls demolished in the 1960s. The municipal area contains six core urban districts, eight suburban districts, and two rural counties, though the administrative structure has been reorganized multiple times since 1949. Population figures from the seventh national census conducted in 2020 recorded 21.89 million permanent residents within Beijing municipality, though estimates of the floating population of unregistered workers add several million more during peak construction and service seasons.
The city functions as the seat of the National People's Congress, the State Council, and the Central Military Commission, with Zhongnanhai compound west of the Forbidden City serving as the central headquarters for the Communist Party of China and the residence location for top leadership since 1949. Beijing holds direct-controlled municipality status, giving it provincial-level administrative authority equivalent to Shanghai, Tianjin, and Chongqing rather than reporting through a provincial government. The mayor reports directly to the State Council. Sixteen administrative subdivisions within the municipality range from the dense urban core of Dongcheng and Xicheng districts to the mountainous terrain of Miyun and Huairou districts in the northeast. The Sixth Ring Road, completed in 2009, spans approximately 187 kilometers in circumference and marks a rough boundary between heavily urbanized areas and the transition to agricultural and conservation zones.
Three thousand years of continuous settlement history begins with the establishment of the city of Ji during the Western Zhou Dynasty around 1045 BCE, serving as the capital of the vassal state of Yan. The Jurchen Jin Dynasty moved its capital here in 1153, renaming it Zhongdu and constructing it on a site slightly southwest of the current city center. Mongol forces under Genghis Khan destroyed Zhongdu in 1215, and Kublai Khan later built a new capital called Dadu on a site overlapping with modern Beijing, completed between 1264 and 1293. The Yuan Dynasty capital followed a grid pattern aligned with cardinal directions, a layout template that influenced all subsequent iterations. The Ming Dynasty captured Dadu in 1368 and initially moved the capital to Nanjing, but Emperor Yongle relocated it back north in 1421, renaming the city Beijing meaning "Northern Capital." The Forbidden City construction began in 1406 and concluded in 1420, employing an estimated one million workers and 100,000 artisans over fourteen years. The Ming rebuilt the city walls to a perimeter of approximately 24 kilometers, with nine gates controlling entry.
The Qing Dynasty captured Beijing in 1644 and retained it as the imperial capital for 268 years until the abdication of Puyi in 1912, though they maintained the Manchu residential restrictions in the Inner City that forced Han Chinese into the Outer City south of Qianmen Gate. The Republic of China established Beijing as the capital until the Nationalist government moved to Nanjing in 1928, at which point the city was renamed Beiping meaning "Northern Peace." Japanese occupation from 1937 to 1945 restored the name Beijing. The Communist forces took control on January 31, 1949, and Mao Zedong proclaimed the founding of the People's Republic from Tiananmen Gate on October 1, 1949, reestablishing Beijing as the national capital. The subsequent three decades saw massive restructuring including the demolition of the majority of the city wall system between 1965 and 1969 to make way for the Second Ring Road and the Beijing Subway Line 2, which follows the wall's former path.
The Forbidden City occupies 72 hectares in the center of Beijing and served as the imperial palace for 24 emperors across the Ming and Qing dynasties from 1420 to 1912. The complex contains 980 surviving buildings encompassing approximately 8,700 rooms, though traditional sources claim 9,999 rooms based on symbolic numerology. The main axis runs north-south for 961 meters, and the east-west width measures 753 meters. A 52-meter-wide moat and 7.9-meter-high walls surround the entire complex. The Palace Museum established in 1925 now administers the site and reported 19.3 million visitors in 2019 before pandemic restrictions reduced access. UNESCO inscribed the Forbidden City as a World Heritage Site in 1987 under criterion for being a masterpiece of Chinese palatial architecture and the political and ritual center for five centuries. The three main halls of the Outer Court serve as the ceremonial core: the Hall of Supreme Harmony sits on a three-tiered marble terrace and measures 63 meters wide by 37 meters deep with a height of 35.5 meters, making it the largest wooden structure within the complex. The Inner Court served as the imperial residential quarters, with the Palace of Heavenly Purity functioning as the emperor's bedchamber during the Ming Dynasty before becoming an audience hall under the Qing.
Tiananmen Square extends 880 meters north to south and 500 meters east to west, covering 440,000 square meters and ranking as one of the largest public squares by area globally. The square in its current form dates to expansion projects in 1949 and 1959 rather than representing a traditional imperial space. The Gate of Heavenly Peace (Tiananmen) forms the northern edge, built originally in 1420 and rebuilt in 1651 after fire damage. Mao Zedong's portrait has hung on the gate since 1949, replaced annually before National Day on October 1. The Monument to the People's Heroes occupies the center of the square, completed in 1958 and standing 37.94 meters tall with eight bas-relief panels depicting revolutionary events. The Chairman Mao Memorial Hall on the southern edge opened in 1977 and displays Mao's embalmed body in a crystal coffin, with reported visitation exceeding 200 million people since opening. The National Museum of China occupies the eastern side in a building expanded and renovated in 2011 to provide 192,000 square meters of exhibition space across 48 galleries, making it one of the largest museum buildings by floor area. The Great Hall of the People on the western edge serves as the meeting place for the National People's Congress and contains a main auditorium seating 10,000 people, completed in ten months during 1959.
The Temple of Heaven complex covers 273 hectares in the southern Dongcheng District, roughly four times the area of the Forbidden City, though the built structures occupy a small fraction of the total park space. Construction occurred from 1406 to 1420 under the Yongle Emperor simultaneously with the Forbidden City. The Hall of Prayer for Good Harvests stands 38 meters tall and 30 meters in diameter, built entirely without nails using a system of interlocking wooden brackets and columns arranged in three concentric rings representing heaven, earth, and humanity. The building burned in 1889 after a lightning strike and was reconstructed in 1890 following the original design. The circular three-tiered Altar of Heaven measures 5.2 meters high and 54 meters in diameter at the base level, constructed entirely from marble and designed for the winter solstice sacrifices performed by the emperor. The number of stones in each tier follows multiples of nine, considered the most auspicious yang number, with the top tier containing 9 rings of stones, the middle tier 18, and the bottom tier 27. The Echo Wall forms a circular enclosure 193 meters in circumference with acoustic properties that allow whispers to travel along the wall's surface to listeners on the opposite side, though visitor numbers now typically prevent practical demonstration of this effect.
The Summer Palace occupies 290 hectares in the northwestern Haidian District, with Kunming Lake comprising approximately three-quarters of the total area at 220 hectares. Empress Dowager Cixi ordered the reconstruction and expansion between 1886 and 1895 using 30 million taels of silver nominally allocated for naval modernization. The complex originated as the Garden of Clear Ripples built by the Qianlong Emperor between 1750 and 1764, but Anglo-French forces destroyed most structures in 1860 during the Second Opium War. The Long Corridor runs 728 meters along the northern shore of Kunming Lake, supported by 273 sections divided by crossbeams, with over 14,000 paintings decorating the ceiling beams and crossbeams depicting landscapes, flowers, birds, and scenes from classical literature. The Marble Boat sits at the western end of the Long Corridor, rebuilt by Cixi in 1893 with a superstructure of painted wood designed to resemble marble, measuring 36 meters in length. Longevity Hill rises 60 meters above lake level and contains multiple temples and halls ascending the slope, culminating in the Buddhist Fragrance Pavilion at the summit, an octagonal structure standing 41 meters tall. UNESCO designated the Summer Palace a World Heritage Site in 1998 for representing a masterpiece of Chinese landscape garden design.
Beihai Park covers 69 hectares north of the Forbidden City, with the lake comprising 39 hectares and Jade Flowery Islet occupying 6.7 hectares in the center of the lake. The park originated in the 10th century during the Liao Dynasty as an imperial garden, expanded significantly under the Jurchen Jin Dynasty, and received major additions during the Yuan, Ming, and Qing dynasties, making it among the oldest surviving imperial gardens. The White Dagoba on Jade Flowery Islet stands 35.9 meters tall in the Tibetan Buddhist stupa style, constructed in 1651 to commemorate a visit by the Fifth Dalai Lama. The Nine-Dragon Screen near the park's north entrance stretches 25.5 meters long, 6.6 meters high, and 1.2 meters thick, built in 1756 using colored glazed tiles forming nine complete dragons among clouds and waves. The Round City near the southern entrance contains a 1.5-meter-tall jade urn carved from a single piece of black jade during the Yuan Dynasty, weighing approximately 3,500 kilograms and used for storing wine. The park opened to the public in 1925 after the expulsion of the last Qing emperor from the Forbidden City.
The Ming Tombs lie 50 kilometers northwest of central Beijing in a valley at the foot of Tianshou Mountain, containing the mausoleums of thirteen Ming Dynasty emperors beginning with the Yongle Emperor and ending with the Chongzhen Emperor, spanning 1409 to 1644. The entire necropolis covers 40 square kilometers and follows feng shui principles with mountains to the north and a river flowing past the entrance to the south. The Spirit Way approaching the tombs extends seven kilometers and features twelve pairs of stone statues including lions, camels, elephants, horses, and mythical creatures, followed by statues of military and civil officials. The Changling tomb of the Yongle Emperor remains the largest and best preserved, with excavation of its surface structures revealing the Hall of Eminent Favor measuring 67 meters wide and 29 meters deep, supported by 32 massive nanmu wood columns, each trunk transported over 3,000 kilometers from forests in present-day Guizhou or Yunnan. Only the Dingling tomb of the Wanli Emperor has been archaeologically excavated, opened between 1956 and 1958 to reveal an underground palace 27 meters below ground level containing five vaulted chambers built entirely from stone without beams or pillars. UNESCO inscribed the Ming Tombs as a World Heritage Site in 2003 as an extension of the earlier listing for the Ming and Qing Imperial Tombs.
Hutongs describe the narrow alleyways and courtyard neighborhoods formed during the Yuan Dynasty and expanded under subsequent dynasties, traditionally oriented along east-west axes with courtyard homes facing south. The term derives from the Mongolian word "hottog" meaning well, as neighborhoods formed around water sources. At peak extent in the 1950s, Beijing contained over 6,000 named hutongs, though urban redevelopment reduced this number below 1,000 by 2020. Courtyard homes followed a standard layout with a gate house facing south, an inverted U-shaped main building, and side wings enclosing a central courtyard, with wealthier families constructing multiple connected courtyards arranged along a north-south axis. Alley widths typically measured three to four meters for cart access, while smaller lanes less than two meters wide allowed only pedestrian traffic. The Shichahai area north of Beihai Park retains one of the largest continuous hutong districts, though conversion of courtyard homes to commercial uses altered traditional residential patterns. Nanluoguxiang hutong running north-south for 786 meters dates to 1267 during the Yuan Dynasty and preserves the original urban grid layout with eight parallel hutongs extending east and west.
The National Stadium, known colloquially as the Bird's Nest, occupies 258,000 square meters in the Olympic Green developed for the 2008 Summer Olympics in the northern Chaoyang District. The steel structure weighs 42,000 tons arranged in a lattice pattern suggested by the crazing on Chinese ceramics, designed by Herzog and de Meuron in collaboration with Chinese artist Ai Weiwei and engineer Arup. The stadium measures 330 meters long, 220 meters wide, and 69 meters tall, with a capacity reduced from the original Olympic configuration of 91,000 seats to a permanent 80,000 seats. Construction cost approximately 3.5 billion yuan at 2008 exchange rates. The adjacent National Aquatics Center, called the Water Cube, covers 79,532 square meters with a steel space frame wrapped in ETFE cushions forming 3,065 bubbles, inspired by research into soap bubble formations. The facility converted to the Ice Cube for curling events during the 2022 Winter Olympics through addition of a curling facility beneath the swimming pools.
Beijing Capital International Airport, located 26 kilometers northeast of central Beijing in Shunyi District, served as the primary international gateway from 1958 until the opening of Beijing Daxing International Airport in 2019. Terminal 3 opened in 2008 before the Olympics and covers 986,000 square meters, ranking among the largest airport terminal buildings globally, designed by Foster and Partners with a dragon-themed roof featuring skylights in red and gold. The airport handled 100.98 million passengers in 2019 before pandemic impacts. Beijing Daxing International Airport opened on September 25, 2019, positioned 46 kilometers south of Tiananmen Square straddling the border between Beijing's Daxing District and Hebei's Langfang. The terminal building designed by Zaha Hadid Architects covers 700,000 square meters under a single roof, with six curved spokes radiating from a central courtyard to minimize walking distances, targeting an ultimate capacity of 100 million passengers annually. The airport rail link connects to the Daxing Airport station on the south end of Beijing Subway Line 4, covering the distance in 20 minutes at speeds reaching 160 kilometers per hour.
The Beijing Subway opened its first line on October 1, 1969, running 23.6 kilometers from Beijing Railway Station to Gucheng with an initial purpose of civil defense and military transport before opening to the general public on January 15, 1971. As of 2024, the network encompasses 27 operational lines covering 783 kilometers with 459 stations, ranking as the second-longest metro system globally by route length after Shanghai. The network carried 3.85 billion passenger trips in 2019, averaging 10.55 million trips per weekday. Flat-fare pricing adopted in 2007 charged 2 yuan per trip regardless of distance, but distance-based pricing reinstated in 2014 now charges 3 yuan for trips up to 6 kilometers, with incremental increases reaching 7 yuan for trips between 22 and 32 kilometers and 8 yuan for trips between 32 and 42 kilometers, capping at 9 yuan for longer distances. Line 10 forms a loop serving the area inside the Third Ring Road with 45 stations over 57.1 kilometers. Line 1 runs east-west through the city center passing Tiananmen Square and carrying over one million passengers daily during peak years, with portions of the track and infrastructure unchanged since the 1969 opening.
