A Historic New England property and National Historic Landmark, Otis House was designed by Charles Bulfinch for Harrison Gray Otis, a lawyer who was instrumental in developing Beacon Hill, served in Congress and was a mayor of Boston. The house reflects the classical proportions and delicate detail of the Federal style and is the last surviving mansion in Bowdoin Square. The restoration of Otis House and its brilliantly colored wallpapers, carpeting, and high-style furnishings is based on meticulous historical and scientific research.
