The Armour-Stiner (Octagon) House is one of the most visually unique homes in the world. It is also the only known fully domed octagonal residence and the only house that replicates Donato Bramante’s 1502 Tempietto in Rome. It contains the only remaining Egyptian Revival room in an American home with its original 1876 furnishings. From 1940 to 1976, it was owned by Carl Carmer, the famed author, poet, and historian. Shortly after Carmer's death, the house was acquired by National Trust for Historic Preservation. In need of stabilization and conservation, it was the first house to be acquired by the National Trust and resold, in 1978, to a private citizen. Joseph Pell Lombardi, the owner, is a preservation architect specializing in conservation, restoration, and historic preservation throughout the world. Under the direction of Lombardi’s son, Michael Hall Lombardi has managed, researched, and performed restoration work throughout the house, including the Egyptian Revival room, staff kitchen, greenhouse, studio, and many of its decorative surfaces.
