Interesting recreation of a Colonial-Era stockade, originally built in the 1950s as a roadside attraction but now owned by Sullivan County and operated as a museum. Make sure you check its operating hours before you visit -- outside of the summer season they're limited. We visited on a day they were technically closed, but it was open for a school field trip and the docents were kind enough to let my wife and I walk around and give us the full presentation. Not a large site -- don't plan on spending much more than an hour or so here unless you use the nearby picnic shelter for lunch.
