Formerly the home of widow Catherine Hammond Gibson and her son Charles, this six-level structure was designed by Boston architect Edward Clarke Cabot and built 1859-1860. The Victorian-era mansion is a wonderful example of the American row house and has retained its formal rooms and quarters, containing family heirlooms, art and furniture. Admission: $3-9. Open for guided tour only W-Su at 1 pm, 2 pm and 3 pm.
