Preserving the Past: How a 1956 Candlelight Tour Launched Arlington’s Historical Movement
The November gathering at the historic hilltop mansion was designed to generate public interest in this new preservation mission. Agnes Downey (later Agnes Downey Mullins) led the specialized tour of the antebellum estate and served as the National Park Service (NPS) resident site historian. A founding member of the Arlington Historical Society, Downey was already becoming a central figure in the mid-century Washington-area historic preservation movement.
- Arlington House Authority: Alongside researcher Murray Nelligan, Downey conducted the extensive, definitive primary source research used to map out how the mansion looked and functioned in the mid-19th century.
- The Arlington House Furnishing Plan: She later authored the site’s critical 1979 historic furnishing guidelines, dictating how the estate’s artifacts are treated and displayed to this day.
- The Old Stone House: Demonstrating her versatility across regional historic preservation, Downey also went on to serve as the very first curator for The Old Stone House in Georgetown, Washington, D.C.
Drawing on her ongoing research, she detailed the house’s structural evolution and shared insights into the daily lives of its former residents, including the Custis and Lee families. The unique presentation style let members experience the historic site as it appeared before modern utilities, highlighting the educational, immersive approach the society aimed to bring to the county.
