Opened in 1839, Green Mount is an early example of an urban-rural cemetery, that is, a cemetery with a park-like setting located close to the countryside. Green Mount is the final resting place of some of Maryland’s most famous, and infamous, figures including Johns Hopkins, Enoch Pratt, William and Henry Walters, Mary Elizabeth Garrett, Betsy Patterson, A.S. Abell, John H. B. Latrobe, John Wilkes Booth, and Elijah Bond, who patented the Ouija Board!
