The Parmenter Barn is a classic example of a New England post and beam dairy barn, with a door on each end, a central floor, and a bay on each side for animal stalls and hay storage. John Blood built the barn in 1859, where 23A High Range Road is today. In 1910 the family sold the barn to Edward and Ralph Parmenter.
In 1998 the Historical Society moved and later re-assembled the barn piece by piece. It houses some of the LHS collections and is available for rental for events.
