Central Park is an urban park in middle-upper Manhattan, within New York City. Central Park is the most visited urban park in the United States, with 40 million visitors in 2013. It is also one of the most filmed locations in the world.The Park was established in 1857 on 778acre of city-owned land. In 1858, Frederick Law Olmsted and Calvert Vaux, a landscape architect and an architect, respectively, won a design competition to improve and expand the park with a plan they titled the “Greensward Plan”. Construction began the same year and the park’s first area was opened to the public in the winter of 1858. Construction continued during the American Civil War farther north, and was expanded to its current size of 843acre in 1873.Central Park was designated a National Historic Landmark (listed by the U.S. Department of the Interior and administered by the National Park Service) in 1962. The Park was managed for decades by the New York City Department of Parks and Recreation, and is currently managed by the Central Park Conservancy under contract with the municipal government in a public-private partnership. The Conservancy is a non-profit organization that contributes 75 percent of Central Park’s $65 million annual budget and is responsible for all basic care of the 843-acre park.
