Under the direction of William Clark, Fort Osage was built in 1808 and functioned as an outpost in the newly acquired Louisiana Purchase and protected the US Factory Trade House there. It aided the American govenment in befriending Osage Indians and offered Missouri's early settlers and explorers a sanctuary from which to venture westward. The buildings are reproductions of the original Fort buildings. They have been painstakingly rebuilt according to detailed plans of similar forts preserved
