Fort Duquesne is a historical French former fur trade post. It was built c. 1750 and was first discovered in 1983. The following year, on November 15, 1984, the site was added to the National Register of Historic Places. The site is about two miles north of Little Falls, on the west side of the Mississippi River. Since 2004, the site is part of the Charles A. Lindbergh State Park, as a result of a law passed by the Minnesota Legislature.
