10. Glebe House and Gertrude Jekyll Garden, Woodbury, CT

The combination of this original farmhouse and stunning Gertrude Jekyll Gardens come together to create one of the most authentic house museums in Connecticut. The Glebe House is a historic farmhouse built in 1740 in the Litchfield Hills and is an excellent representation of Revolutionary War-era Connecticut. The Glebe House was originally the family home of Reverend John Rutgers Marshall and his family. Shortly after American independence was won, Connecticut clergy members met at the Glebe House to work towards the building of an America that allowed their religious beliefs. The surrounding Gertrude Jekyll Garden is the only existing American garden planned by Gertrude Jekyll, who was a famous English garden designer.

12. Scoville Memorial Library, Salisbury, CT

The Scoville Memorial Library is the first publicly funded library in the United States and its creation began in 1771 when a local citizen offered to bring 200 books back from London. The free public library grew in 1805 when additional books were added to the collection by Caleb Bingham. The books were moved into the Scoville Library when a Salisbury native left money to the town for the building of a library to house the ever-growing collection of books. The library has since added on additional space and its collection of books is now over 30,000.

13. Osborne Homestead Museum, Derby, CT
