Fort Osage National Historic Landmark

About Fort Osage

Step back in time, back to when Missouri was way out West in the wilderness, and experience the lives of the men and women who secured the American frontier.

Built in 1808, under the direction of William Clark, co-leader of the Lewis and Clark expedition, the Fort served a dual role. It was both a military garrison and trade center.

Overlooking the Missouri River, this historic site was reconstructed in the 1940's to portray Fort Osage as it was in 1812. Authentically attired interpreters provide living-history insights into the daily life of both the military and civilian populations.
