President Calvin Coolidge was born in Plymouth Notch, VT and is buried there. His modest Homestead and the Historic District of Plymouth Notch is one of few Vermont State Historic Sites. There are about 16 interesting structures to visit there, and some special events all summer long including special celebrations for July 4th, the anniversary of his birthday. He is actually the only U.S. president born on July 4th. Interestingly enough, his home in Plymouth Notch is also the place where he was sworn as the 30th president of the United States, upon the death of President Warren Harding.
Additionally, Frog City Cheese is still manufacturing Plymouth Cheese there, following the tradition of the first cheese maker established there at the end of the 19th century (President Calvin Coolidge's father was one of the founders!) and you can observe how cheese is made, visit the museum with the original equipment and the store.
Overall a very interesting place to visit and spend an afternoon.
