Old Stone Fort

This is an historic site in Schoharie Village featuring «The Old Stone Fort» (more below), an historical cemetery, and a half a dozen historical buildings that have been relocated here to make a mini-​historical park.
The Old Stone Fort complex is open from late May to September most days, and closes up for the winter shortly after labor day. Hours seem to be mostly 10 AM to 4 PM. Admission to the main building is $ 7 for adults, $ 2 for kids, free for kids under 5, with some AAA and seniors discounts. You can wander around the other buildings but it’s an honor system.
The staff wear historical outfits but don’t do full re-​enactment style interpretation; most of the exhibits are self-​guided. There’s a small gift shop inside with a pleasant assortment of historical and touristy things that are sold to support the historical society.
The Old Stone Fort was a church that was reinforced and put inside a stockade during the French and Indian and Revolutionary Wars. The stockade has not been restored, and the site has been festooned with memorials since the 19^th century, so it is not a particularly instructive example of the fortified household that was common during the conflicts on the western frontier of New York. That said, it serves as one of the few spots where you can see remnants of what the brutal warfare of the Revolution here was like (where Loyalist and Indians, and Patriots and Indians, traded wars of obliteration, destroying every house and farm and murdering men, women, and children alike wholesale as a war of economic attrition). The Old Stone Fort was one of a series of structures that served as refuges for Patriot settlers during a series of armed raids (bordering on massacres), and was the site of an engagement in 1780 during a large-​scale pillaging of the Schoharie Valley by (loyalist) Sir John Johnson and (Mohawk) Captain Joseph Brant that targeted the patriot-​Palatine German settlers and their Oneida allies close by. The British besieged several hundred militia and their families inside the stockade for a short period, and then left; the Patriots couldn’t stop them from destroying the valley, but the Fort saved their lives.
There’s little in the fort to show this, though, as it’s devoted to a hodge podge of artifacts donated over nearly 200 years, ranging from some authentic remnants of the Revolution (muskets, axes, etc.) to Civil War paraphernalia dating from its latter use as an armory to arm and train New York regiments and some truly unrelated items in between. The upstairs has case after case of miscellany, from arrowheads to old newspapers, that is only thinly curated. You will likely find things of interest but it’s hard to really take in an ordered way and there’s no «story» in the exhibit organization.
As such, I wouldn’t go out of your way to visit this place «cold» without reading up a little on the bitter frontier warfare of 1776 – 1781; without the context it’s just a semi-​cool old building with some cannons in front, with the context you can feel the shivers running down your spine as you realize this building was a refuge from torture, mutilation, and slow death of the worst kind.
The outbuildings have various levels of interest. The best are an old school house where the kids can pretty much play school, 19^th-​century style (including ringing the school bell from a rope) and an old barn with a really monumental number of miscellaneous farm implements from over a 200 year period, again, sort of semi-​randomly organized.
If you’d like to see the same sort of thing on a somewhat grander and more historically important scale, I’d suggest Johnson Hall /​Old Fort Johnson state historic site in Johnstown –formerly the county seat of Troyon County, which was pretty much everything in New York that wasn’t New York City or Albany before indpendence, and pretty much the center of New York’s western frontier leading up to the Revolution — or the Fort Stanwix National Historical Monument near Rome, associated with the bloody Oriskany campaign, which has a full modern recreation of a much larger stockade fort built using original archeological information.
