Central Park is an urban park in Manhattan. It comprises 843 acres (341 ha) between the Upper West Side and Upper East Side, roughly bounded by Fifth Avenue on the east, Central Park West (Eighth Avenue) on the west, Central Park South (59th Street) on the south, and Central Park North (110th Street) on the north. Central Park is the most visited urban park in the United States, with 40 million visitors in 2013, and one of the most filmed locations in the world.
The park was established in 1857 on 778 acres (315 ha) of land acquired by the city. In 1858, landscape architect Frederick Law Olmsted and architect/landscape designer Calvert Vaux 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 north of the park continued during the American Civil War in the 1860s, and the park was expanded to its current size in 1873.
