Fort Frye - Credit: Wikimedia Commons
Fort Frye was a triangular defensive fortification built by a group of pioneers from the Ohio Company of Associates who moved about twenty miles up the Muskingum River from the settlement of Marietta, Ohio to a location near the mouth of Wolf Creek. During 1789 the pioneers established settlements now known as Waterford and Beverly on the southwest and northeast banks of the Muskingum, respectively. The settlements were located about 13 miles downriver from a small group of pioneers at Big Bottom. During January and February 1791, following the massacre at Big Bottom and the start of the Northwest Indian War, the settlers built Fort Frye at Beverly. Read more on Wikipedia
