An emerald expanse in the thriving, concrete jungle that is New York City, Central Park lies in the heartland of the Manhattan borough. It commences its labyrinthine stretch from Midtown, all the way to Harlem. It was created in 1857 by Frederick Law Olmsted and Calvert Vaux, who envisioned a sprawling green space in the center of the island. The park spans 843 acres (341.15 hectares) and bustles with life throughout the day, even as the layered, multi-hued fold of the city's skyline unfolds at its hem. The park's 21 playgrounds are speckled with ornate fountains, sculptures, myriad bridges and arches, together forming an urbane respite where several come to find peace from the city's chaotic pace. Attractions within the park include the Bethesda Fountain, the Conservatory Garden, Belvedere Castle, and Central Park Zoo.
