Fort Harmar, Military fort site in Marietta, United States.
Fort Harmar stood at the junction of Ohio and Muskingum rivers, constructed in a pentagon shape with timber walls reaching 14 feet in height.
Built in 1785 under Colonel Josiah Harmar's command, the fort served as a strategic base to prevent unauthorized settlement north of the Ohio River.
The fort became a center for negotiations between the United States government and Native American tribes, leading to the 1789 Treaty of Fort Harmar.
The fort's location on the west bank of the Muskingum River provided military control over both waterways and facilitated the monitoring of river traffic.
Major Ebenezer Denny and Joseph Buell documented daily activities at Fort Harmar through detailed journals spanning four years of military operations.
