Located on a broad rolling plain at the northern edge of the town of Westfield, the Beecher H. Duncan Farm is a good example of a type of family farm that was established in Aroostook County in the early 20th century. The small collection of agricultural and residential buildings and fields were established by the Beecher family at a time when agricultural enterprises, especially the cultivation of potatoes, were rapidly developing, and large amounts land was available for sale. This small historic district includes a large gambrel roof hay barn (1910), a vernacular style house with Queen Anne stylistic elements, an earlier cottage used periodically to house workers on the farm and a broad expanse of agricultural fields. It was eligible for listing in the National Register of Historic Places in the area of agriculture as a property that reflects broad agricultural trends between 1904 and 1950 in Aroostook County. The property also reflects the wholesale change from horse-powered farming to mechanized farming in the years before World War II.
