Rich Hill, near Bel Alton, Maryland, was owned by Colonel Samuel Cox, a Confederate sympathizer during the American Civil War.

Following the assassination of President Abraham Lincoln on April 14, 1865, Cox hid assassin John Wilkes Booth and his companion, David Herold, in a swamp near Rich Hill.

Booth and Herold left the property on April 21, crossing the Potomac River in a small boat.

It was listed on the National Register of Historic Places in 1975.
