In 1838, Brooklyn's Green-Wood Cemetery followed the garden cemetery movement pioneered in the United States by Cambridge's Mount Auburn. These burial grounds didn't belong to churches, but used the beauty of their landscaping to attract clientele. Sightseers took trains from Manhattan merely to walk Green-Wood's 20 miles of paths and admire its statuary, sit by its fountains, and gaze at its views. In 1860 alone, the cemetery pulled in half a million visitors: a tourist attraction second only to Niagara Falls in all of North America.
