National Historic Landmark - Fort Osage

The site of Fort Osage sits on a 70-foot-high bluff overlooking a bend in the Missouri River. Captain William Clark noted this remarkable natural location on the Missouri River in his journal: “A high commanding position, more than 70 feet above high water mark, and overlooking the river which is here of but little width; this spot has many advantages for a fort, and trading house with the Indians."

In 1808, after the completion of the expedition, Clark returned and constructed Fort Osage as both a military outpost and trading factory for the newly-formed Missouri Territory. The fort's goal was to provide a military presence along the frontier, while maintaining political stability through economic and military alliances with the American Indian tribes in the territory.  The most notable of these groups were the Osage or Wabasha.

The current Fort Osage is a replica of the original fort, which was decommissioned in 1827. Reconstruction of the fort, began in 1941 by the Jackson County Court and the Native Sons of Kansas. It was through their diligence and research that they reconstructed Blockhouse No.1 and officially dedicated it in 1946. In 1961, the site earned the National Historic Landmark designation and reconstruction was completed in the 1960s.  In 2007, the Fort Osage Educational Center opened with permanent interactive exhibitions on American Indians, Lewis and Clark, and the fort. The Center provides an extensive array of living history interpretation, tours, visiting exhibitions, and archaeological activities.
