Greenwood Cemetery was founded in 1838 and was a huge tourist attraction in the 1860's (this was before the creation of public parks, so it was one of the few landscaped green spaces New Yorkers could visit. Apparently, there were carriage rides and other attractions). Today, you can visit the rolling hills and get a free glimpse at some pretty amazing architectural monuments. Some may find it creepy, but I thought it was fascinating.
