Marietta House Museum

Marietta, the Federal-style brick home of U.S. Supreme Court associate justice Gabriel Duvall, is listed on the National Register of Historic Places. Built ca. 1813, Marietta remained under the ownership of the Duvall family until 1902. The home is situated on 25 acres of lawn and wooded areas and the grounds boast two County Champion trees, a lovely old boxwood and a bamboo grove.


The Marietta Museum focuses on exhibits relevant to Prince George’s County history and on special events and programs such as period re-enactments, afternoon teas and children’s storytelling hours. The Society of Mareen Duvall Descendants has relocated the family graveyard from its original location to the serene surroundings at Marietta. Justice Duvall's law office and root cellar also are open to the public.
