Picketed Point Stockade was the last of three fortifications built at Marietta, Ohio. This defensive stockade was built by pioneers during the Northwest Indian War in 1791 on the east side of the mouth of the Muskingum River at its confluence with the Ohio River, and directly across the Muskingum from Fort Harmar. Colonel William Stacy superintended the construction of the stockade under direction of Colonel Ebenezer Sproat. Palisades or pickets were set from the Muskingum River eastward, meeting in the northeast corner of the fortification with another line of pickets built from the Ohio River northward, enclosing about four acres.
