Otis House (1796) is the last surviving mansion in Bowdoin Square in Boston’s West End neighborhood. Otis House is a National Historic Landmark, and the home of the Historic New England Library and Archives.
Charles Bulfinch designed the house for Harrison Gray Otis, a lawyer who was instrumental in developing nearby Beacon Hill, served in Congress, and was a mayor of Boston. It is the first of three houses Bulfinch designed for Otis and his wife, Sally Foster Otis.
The house reflects the classical proportions and delicate detail of the Federal style.
