Fort McIntosh

Fort McIntosh is an archaeological site in Beaver, Pennsylvania where excavations since 1974 have uncovered over 80,000 artifacts. The remains include original stone wall footers, fireplaces, granite monuments, and bronze plaques that mark the fort's historical importance.

The fort was built in 1778 under French engineer Lt. Col. Cambray-Digny and served as the first Continental Army installation north of the Ohio River. A treaty signed here in 1785 addressed territorial agreements with eastern nations and their land claims in the region.

The Treaty of Fort McIntosh, signed at this location in 1785, established agreements with Native American nations for western territorial expansion.

The site is maintained by the Beaver Area Heritage Foundation and is open for public viewing of the excavated remains and monuments. Visitors should expect to see primarily foundations and excavation areas, as the location is largely outdoors and subject to weather conditions.

The fort housed the First American Regiment, a military unit that continues to exist today and serves in ceremonial roles in Washington. This direct connection between an early Revolutionary garrison and a modern military institution is rarely documented at other historical sites.
