Central Park Planet (New York) Editorial Image

Central Park is a public park in the center of Manhattan in New York City, United States. 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 and was completed in 1873. Designated a National Historic Landmark in 1963, the park is currently managed by the Central Park Conservancy under contract with the city government. The Conservancy is a nonprofit organization that contributes 85% of Central Park's $37.4 million dollar annual budget, and employs 80% of the park's maintenance staff.
