Fort Greene is a neighborhood in the New York City borough of Brooklyn. Fort Greene is listed on the New York State Registry and on the National Register of Historic Places, and is a New York City-designated Historic District. It is located in north west Brooklyn, above Prospect Park. Washington Park, renamed Fort Greene Park in 1897, was established as Brooklyn's first park in 1847 on a 30-acre (120,000 m2) plot around the site of the old Fort. In 1864, Frederick Law Olmsted and Calvert Vaux, by now famous for their design of Central Park, were contracted to design the park, and constructed what was described in 1884 as "one of the most central, delightful, and healthful places for recreation that any city can boast." Olmsted and Vaux's elegant design featured flowering chestnut trees along the periphery, open grassy spaces, walking paths, a vine-covered arbor facing a military salute ground, a permanent rostrum for speeches, and two lawns used for croquet and tennis. The park's success prompted the creation of the larger Prospect Park. At the highest point of the park, The Prison Ship Martyrs Monument and vault was erected in 1908 to house the bones of some of the 12,000 Revolutionary soldiers and civilians whose bodies were thrown off British prison ships and later washed ashore. The monument, designed by the firm of McKim, Mead, and White, was the world's largest Doric column at 143 feet (44 m) tall, and housed a bronze urn at its apex. Restoration work is currently under way to restore the monument and will be complete in the fall of 2007.
