Located at the corner of present-day Congress Street and Colchester Street marks the site where the oldest framed house in Amesbury once stood. William Osgood built the original house in 1650. In 1969, the house was disassembled and moved to Dover, MA, in spite of the efforts of the AIA and others to save it. New owners bought the land and built the present home.
The present stone marker was erected by the AIA in 1970.The plaque says, “Osgood House 1650 on this site William Osgood built the first framed house for his home and a garrison. Removed and restored in Dover Mass, 1969. Erected by Amesbury Improvement Association, 1970.”
