[THIS TOUR IS NOW SOLD OUT] Before this Oak Hill location became Mount Ida College and then a campus of the University of Massachusetts Amherst, it was the 19th century estate of William Sumner Appleton. Its next owner, Robert Gould Shaw II, named it “Boulder Farm,” and made it the headquarters for his lavish lifestyle during the Gilded Age. This tour shows you the mansion that Shaw commissioned for himself, an 18th century farmhouse that is the second oldest residence in Newton, and other buildings repurposed for campus life. Fee: $15 per person, Historic Newton members, $10.
