Maggie's Farm is a state of mind, and doesn't really represent a single literal farm, as The Barrister has said.
At the same time, to add some ambiguity to the idea, it is partly inspired by a literal farm which was given as a land grant by King George lll to my ancestors, many of whom are buried in the graveyard by the side of the road. It is in the Massachusetts Berkshire Hills, and close enough to Tanglewood for convenience, but I will not say where.
It is remarkable that a place should be in the family, fully intact, after all of these years, although the original farmhouses burned down (cellar-holes still in place) and many of the barns, buildings, and the marble-cutting mill by the river have fallen down over the years.
Much of our stone is marble up here, and much of it was quarried in the first half of the 1800s and pulled by oxen to be floated down the Housatonic River for shipment to NYC, Providence, and Boston for their fancy buildings. All of our barns and buildings have marble foundations beneath their rickety structures. Even the diving "board" at the stream's swimming hole is a 6x4x4 block of marble sticking out into the water which must have been left behind when the last load of marble departed.
The marble was surely a nice income supplement for thse hardscrabble dairy farmers.
One of the two surviving, and gradually being renovated, liveable quarters on the farm was originally built as a rustic and simple dwelling for the mill workers in 1820.
