Central Park is a public park at the center of Manhattan in New York City. The park initially opened in 1857, on 843 acres (3.41 km2) of city-owned land. In 1858, Frederick Law Olmsted and Calvert Vaux won a design competition to improve and expand the park with a plan they entitled the Greensward Plan. Construction began the same year, continued during the American Civil War, and was completed in 1873. Central Park is one of the world’s largest urban public parks comparable to other great parks in the world as for example Paris’ Bois de Vincennes (995 ha; 2,458 acres) and Bois de Boulogne (846 ha; 2,090 acres), London’s Richmond Park (955 ha; 2,360 acres), Madrid’s Casa de Campo (1,723 ha; 4,256 acres), Los Angeles’ Griffith Park (1,740 ha; 4,310 acres).Designated a National Historic Landmark in 1962, the park is currently managed by the Central Park Conservancy under contract with the city government. The Conservancy is a non-profit organization that contributes 83.5% of Central Park’s $37.5 million dollar annual budget, and employs 80.7% of the park’s maintenance staff.
Central Park is bordered on the north by West 110th Street, on the south by West 59th Street, on the west by Eighth Avenue. Along the park’s borders, these streets are known as Central Park North, Central Park South, and Central Park West respectively. Only Fifth Avenue along the park’s eastern border retains its name.The park, which receives approximately thirty-five million visitors annually,is the most visited urban park in the United States.It was opened on 770 acres (3.1 km2) of city-owned land and was expanded to 843 acres (3.41 km2; 1.317 sq mi). It is 2.5 miles (4 km) long between 59th Street (Central Park South) and 110th Street (Central Park North), and is 0.5 miles (0.8 km) wide between Fifth Avenue and Central Park West. Its size and cultural position, similar to Munich’s Englischer Garten and London’s Hyde Park, has served as a model for many urban parks, including San Francisco’s Golden Gate Park, Tokyo’s Ueno Park, and Vancouver’s Stanley Park.
