Knox's Headquarters State Historic Site

The Georgian house, constructed in 1754, stands on Old Forge Hill Road with its original architectural elements and period furnishings throughout the interior rooms.

Major General Henry Knox established his military headquarters at this location during the final phase of the Revolutionary War between 1782 and 1783.

The Ellison family operated commercial mills, producing flour that traveled down the Hudson River to New York City and reached international markets.

The historic site welcomes visitors from Memorial Day through Labor Day with guided tours running hourly between 10:00 AM and 4:00 PM Wednesday through Saturday.

The underground raceway system from the original Ellison mill remains visible on the grounds, demonstrating early American industrial engineering methods.
