Following proposals for a large park in Manhattan during the 1840s, it was approved in 1853 to cover 778 acres (315 ha). In 1857, landscape architects Frederick Law Olmsted and Calvert Vaux won a design competition for the park with their "Greensward Plan". Construction began the same year; existing structures, including a majority-Black settlement named Seneca Village, were seized through eminent domain and razed. The park's first areas were opened to the public in late 1858. Additional land at the northern end of Central Park was purchased in 1859, and the park was completed in 1876. After a period of decline in the early 20th century, New York City parks commissioner Robert Moses started a program to clean up Central Park in the 1930s. The Central Park Conservancy, created in 1980 to combat further deterioration in the late 20th century, refurbished many parts of the park starting in the 1980s.
Its size and cultural position make it a model for the world's urban parks. Its influence earned Central Park the designations of National Historic Landmark in 1963 and of New York City scenic landmark in 1974. Central Park is owned by the New York City Department of Parks and Recreation but has been managed by the Central Park Conservancy since 1998, under a contract with the municipal government in a public–private partnership. The Conservancy, a non-profit organization, contributes 75% of Central Park's $65 million annual budget and is responsible for all basic care of the park.
Central Park is divided into three sections: the "North End" extending above the Jacqueline Kennedy Onassis Reservoir; "Mid-Park", between the reservoir to the north and the Lake and Conservatory Water to the south; and "South End" below the Lake and Conservatory Water.The park has five visitor centers: Charles A. Dana Discovery Center, Belvedere Castle, Chess & Checkers House, the Dairy, and Columbus Circle.
The park has natural-looking plantings and landforms, having been almost entirely landscaped when built in the 1850s and 1860s. It has eight lakes and ponds that were created artificially by damming natural seeps and flows. There are several wooded sections, lawns, meadows, and minor grassy areas. There are 21 children's playgrounds,and 6.1 miles (9.8 km) of drives.
Central Park is the most visited urban park in the United States and one of the most visited tourist attractions worldwide, with 42 million visitors in 2016. The number of unique visitors is much lower; a Central Park Conservancy report conducted in 2011 found that between eight and nine million people visited Central Park, with 37 to 38 million visits between them. By comparison, there were 25 million visitors in 2009 and 12.3 million in 1973.
The number of tourists as a proportion of total visitors is much lower: in 2009, one-fifth of the 25 million park visitors recorded that year were estimated to be tourists.The 2011 Conservancy report gave a similar ratio of park usage: only 14% of visits are by people visiting Central Park for the first time. According to the report, nearly two-thirds of visitors are regular park users who enter the park at least once weekly, and about 70% of visitors live in New York City. Moreover, peak visitation occurred during summer weekends, and most visitors used the park for passive recreational activities such as walking or sightseeing, rather than for active sport.
Central Park is patrolled by its own New York City Police Department precinct, the 22nd (Central Park) Precinct, at the 86th Street transverse. The precinct employs both regular police and auxiliary officers. The 22nd Precinct has a lower crime rate than in the 1990s, with crimes across all categories having decreased by 81.2% between 1990 and 2019. The precinct saw one murder, one rape, 21 robberies, seven felony assaults, one burglary, 37 grand larcenies, and one grand larceny auto in 2019. The citywide New York City Parks Enforcement Patrol patrols Central Park, and the Central Park Conservancy sometimes hires seasonal Parks Enforcement Patrol officers to protect certain features such as the Conservatory Garden.
A free volunteer medical emergency service, the Central Park Medical Unit, operates within Central Park. The unit operates a rapid-response patrol with bicycles, ambulances, and an all-terrain vehicle. Before the unit was established in 1975, the New York City Fire Department Bureau of EMS often took over 30 minutes to respond to incidents in the park
There are four different types of bedrock in Manhattan. In Central Park, Manhattan schist and Hartland schist, which are both metamorphosed sedimentary rock, are exposed in various outcroppings. The other two types, Fordham gneiss (an older deeper layer) and Inwood marble (metamorphosed limestone which overlays the gneiss), do not surface in the park. Fordham gneiss, which consists of metamorphosed igneous rocks, was formed a billion years ago, during the Grenville orogeny that occurred during the creation of an ancient super-continent. Manhattan schist and Hartland schist were formed in the Iapetus Ocean during the Taconic orogeny in the Paleozoic era, about 450 million years ago, when the tectonic plates began to merge to form the supercontinent Pangaea. Cameron's Line, a fault zone that traverses Central Park on an east–west axis, divides the outcroppings of Hartland schist to the south and Manhattan schist to the north.
Various glaciers have covered the area of Central Park in the past, with the most recent being the Wisconsin glacier which receded about 12,000 years ago. Evidence of past glaciers can be seen throughout the park in the form of glacial erratics (large boulders dropped by the receding glacier) and north–south glacial striations visible on stone outcroppings. Alignments of glacial erratics, called "boulder trains", are present throughout Central Park. The most notable of these outcroppings is Rat Rock (also known as Umpire Rock), a circular outcropping at the southwestern corner of the park. It measures 55 feet (17 m) wide and 15 feet (4.6 m) tall with different east, west, and north faces. Boulderers sometimes congregate there. A single glacial pothole with yellow clay is near the southwest corner of the park.
The underground geology of Central Park was altered by the construction of several subway lines underneath it, and by the New York City Water Tunnel No. 3 approximately 700 feet (210 m) underground. Excavations for the project have uncovered pegmatite, feldspar, quartz, biotite, and several metals.
Central Park's size and cultural position has served as a model for many urban parks.Olmsted believed landscape design was a way to improve the feeling of community and had intended the park as the antithesis of the stresses of the city's daily life. The Greensward Plan, radical at the time of its construction, led to widespread changes in park designs and urban planning; in particular, parks were designed to incorporate landscapes whose elements were related to each other.
A New York City icon, Central Park is the most filmed location in the world. A December 2017 report found that 231 movies had used it for on-location shoots, more than the 160 movies that had filmed in Greenwich Village or the 99 movies that had filmed in Times Square. Some of the movies filmed at Central Park, such as the 1993 film The Age of Innocence, reflect ideals of the past. Other films, including The Fisher King (1991), Marathon Man (1976), The Out of Towners (1970), and Home Alone 2: Lost in New York (1992), use the park for dramatic conflict scenes. Central Park has been used in romance films such as Maid in Manhattan (2002), 13 Going on 30 (2004) or Hitch (2005), and fantasy live-action/animated films such as Enchanted (2007). In 2009, an estimated 4,000 days of film shoots were hosted, or an average of more than ten film shoots per day, accounting for $135.5 million in city revenue.
Because of its cultural and historical significance, Central Park has been a National Historic Landmark since 1962,and a New York City designated scenic landmark since 1974. It was placed on UNESCO's list of tentative World Heritage Sites in 2017.
In the modern day, it is estimated that Central Park has resulted in billions of dollars in economic impact. A 2009 study found that the city received annual tax revenue of more than $656 million, visitors spent more than $395 million due to the park, in-park businesses such as concessions generated $135.5 million, and the 4,000 hours of annual film shoots and other photography generated $135.6 million of economic output. In 2013, about 550,000 people lived within a ten-minute walk (about 0.5 miles or 0.80 kilometers) of the park's boundaries, and 1.15 million more people could get to the park within a half-hour subway ride.
