Lansdowne is a historic home located at Urbanna, Middlesex County, Virginia. It was constructed about 1740, and is a two-story, five-bay, T-shaped, brick dwelling in the Early Georgian style. It consists of a main section measuring 52 feet by 25 feet, with a rear wing of 36 feet by 18 feet. The front facade features a tall pedimented portico projecting from the center bay. It was the home of diplomat Arthur Lee (1791-1792), who is buried on the property in the family cemetery.[3] Lee helped to negotiate and signed the 1778 Treaty of Alliance, which allied France and the United States together during the American Revolutionary War.
