Central Park /

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 km) 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 $25 million dollar annual budget, and employs 80% of the park's maintenance staff. Central Park, which has been a National Historic Landmark since 1963, was designed by landscape designer and writer Frederick Law Olmsted and the English architect Calvert Vaux in 1858 after winning a design competition. They also designed Brooklyn's Prospect Park. The park, which receives approximately thirty-five million visitors annually, is the most visited urban park in the United States.
