Green Mount Cemetery is a historic cemetery in Baltimore, Maryland, United States. Established on March 15, 1838, and dedicated on July 13, 1839, it is noted for the large number of historical figures interred in its grounds as well as a large number of prominent Baltimore-area families. It retained the name Green Mount when the land was purchased from the heirs of Baltimore merchant Robert Oliver. Green Mount is a treasury of precious works of art, including striking works by major sculptors including William H. Rinehart and Hans Schuler.
The cemetery was listed in the National Register of Historic Places in 1980. Guided tours are available at various times of the year.
A Baltimore City Landmark plaque at the entrance reads:
In addition to John Wilkes Booth, two other conspirators in the assassination of Abraham Lincoln are buried here, Samuel Arnold and Michael O'Laughlen. It is common for visitors to the cemetery to leave pennies on the graves of the three men; the one-cent coin features the likeness of the president they successfully sought to murder.
Until a 1965 agreement with Queen Elizabeth II, the Duke and Duchess of Windsor had planned for a burial in a purchased plot in Rose Circle at Green Mount Cemetery, near where the father of the Duchess was interred. The 1965 agreement allowed for the former King Edward VIII and wife, the Duchess of Windsor, to be buried near other members of the royal family in the Royal Burial Ground near Windsor Castle.
