Green-Wood is 478 spectacular acres of hills, valleys, glacial ponds and paths, throughout which exists one of the largest outdoor collections of 19th- and 20th-century statuary and mausoleums. Four seasons of beauty from century-and-a-half-old trees offer a peaceful oasis to visitors, as well as its 560,000 permanent residents, including Leonard Bernstein, Boss Tweed, Charles Ebbets, Jean-Michel Basquiat, Louis Comfort Tiffany, Horace Greeley, Civil War generals, baseball legends, politicians, artists, entertainers and inventors.

On September 27, 2006, Green-Wood was designated a National Historic Landmark by the United States Department of the Interior, which recognized its national significance in art, architecture, landscaping and history.
