Fort Steuben

Fort Steuben was a fortification erected in Feb. 1787 on the Ohio River in eastern Ohio Country at the northern end of the Seven Ranges land tract to be surveyed. It was at the location of the modern city of Steubenville, Ohio. The fort was built by Major John Hamtramck and named for Friedrich Wilhelm von Steuben, a Prussian army officer who had served under General Washington. The original purpose was to provide protection from Indians for the first surveyors to venture into the Northwest Territory.
