The Historic Fort Stueben is a reproduction fort built upon the site of the original. Dating to 1786, the original fort was built by the First American Regiment for the purpose of protecting surveyors from local Native American groups.

The site includes the First Federal Land Office (an original structure), officers' quarters, enlisted quarters, a quartermaster's office, artificer shop, hospital, and commissary. Topics covered include early Ohio history and the voyage of Lewis and Clarke (1803-1806).

The fort offers tours and demonstrations of surveying, blacksmithing, and flintknapping.
