Greene Place is Brooklyn Technical High School. To the west is the oldest hospital in Brooklyn, Brooklyn Hospital Center. North of the park are the Walt Whitman Houses, one of the largest housing projects in New York City.History and descriptionThe park includes part of the high ground where the Continental Army built fortifications prior to the Battle of Long Island, during the early days of the American Revolutionary War. The site was chosen and construction supervised by General Nathanael Greene; it was named Fort Putnam. During the War of 1812, when the possibility of a British invasion led to the re-use of the site for defense, the newly rebuilt fortification was named Fort Greene in his honor.
