Now headquarters of the Cambridge Historical Society, this is one of two Tory-era homes on Brattle Street fully open to the public. The Emerson family gave it to the society in 1957. Built between 1685 and 1690, the house has been remodeled at least six times, but has maintained much of the original structure. The downstairs is elegantly, although sparsely, appointed with period books, portraits, and wallpaper. An upstairs bedroom has been furnished with period antiques, some belonging to the original residents. Visits are by tour only and run about one hour. A virtual tour of the house is available on the Cambridge Historical Society's website.
