Fort Osage

Located on the banks of the Missouri River in Sibley, Missouri is the site of the historic Fort Osage outpost. Under the direction of William Clark, the fort was constructed in 1808 to serve as a trading post in the newly purchased Louisiana Territory and help build friendships with the Osage Indians. The fort was abandoned by 1827 but was later reconstructed and designated a National Historic Landmark in 1961.

Visitors to Fort Osage will be transported back in time to experience life as an earlier settler of the American frontier. The sweeping views of the Missouri river give an impression of how Lewis and Clark may have felt seeing this wilderness for the first time. Reconstructions of the fort show how living quarters looked when the fort was in use and include a replica of the trading post stocked with typical 1800s trade goods. The Fort Osage Education Center teaches visitors about the history of the fort through museum exhibits and presentations, such as musket firing and period-style cooking demonstrations. Guests fascinated with the supernatural can join paranormal investigators at the fort each October to search out the spirits of the fort’s original residents and families may enjoy the fort’s various living history reenactments or holiday-themed history tours.
