Step into the opulence of yesteryear and tour the Otis House Museum. The house is the last surviving mansion in what used to be Boston's most affluent neighborhood in the 18th century; the man who owned the home, Harrison Gray Otis, was a lawyer who served in Congress and was mayor of the city at one time. The Otis House is still decorated with furnishings that were the best of their time period, including fine furniture pieces and art work.
