Thomas Stone National Historic Site

If you want to see a copy of the Declaration of Independence without all the hustle/​bustle rudeness of the tourists at the Archives in DC, come here.
It’s out of the way and doesn’t get as much tourist traffic as other NPS sites (which is good, because the tour becomes a private tour and you can spend as much or as little time on it because there aren’t lines of people waiting for their turn.)

Very different personality than most of our Founding Fathers, Thomas Stone’s home is worth a visit. Nice tour by nice people… definitely will come by again and highly recommend!

A charming, quiet park near enough to DC to be easily accessible but also far enough away to be in the country.
You hit the visitor’s center, watch a short film about Thomas Stone (a little-​known signer of the Declaration of Independence, and really sounding like a good and thoughtful man), then walk past the little cemetery to the house, where you get a tour of the charming residence, a middle-​class home of the colonial era with its own unique flair.
After that, you’re free to ramble past the farm buildings and the hiking trails on the grounds. This isn’t an all-​day destination but a good diversion for a couple of hours, and is lovely in summer. I want to go back in the fall.
Bring a camera, and a picnic lunch. You’ll learn something about our country’s history and enjoy the outdoors. And it’s all absolutely FREE. Include this on a tour of historic spots in southern Maryland, and have a good time.

Thomas Stone was a signer of the Declaration of Independence and his property, house, and grave are still here and very well maintained, along with some outbuildings and walking trails.
Sadly, I’m not surprised there is no Unilocal entry for this house — apparently it gets one of the least amounts of visitors of any park site. Which makes it an even better place to visit — never anyone there so you can get a guided tour of the place pretty much to yourself, all for free. It isn’t far off of 301 and is well worth a visit.
