Marietta House Museum [MD]
Marietta, the Federal style brick home of Gabriel Duvall, an Associate Justice of the U.S. Supreme Court, is listed on the National Register of Historic Places. Built circa 1813, Marietta remained under ownership of the Duvall family until 1902. Justice Duvall's law office and root cellar still remain today. Marietta is situated on 25 acres of lawn and wooded areas and the grounds boast two County Champion trees and lovely old boxwood. Marietta operates as an historic house museum and is furnished and interpreted to reflect the three generations of Duvall's that occupied the house. The Society of Mareen Duvall Descendants has relocated the family graveyard from its original location to the serene surroundings at Marietta.
The house offers tours, educational programs, workshops, and occasional educational and recreational events.
