Fort Osage National Historic Landmark

Experience the western-most United States military post at the time of its founding in 1808. Walk in the footsteps of William Clark, Captain Eli Clemson, George and Mary Sibley, Sacagawea and Daniel Boone as you walk Fort Osage's historic grounds and view the Missouri River.

Reconstructed on its original site, Fort Osage (1808-1827) is a complex of hewn log structures located on a high bluff overlooking the Missouri River. Living history interpretation is featured year round, as staff and volunteers portray the work and livelihood of Fort Osage area soldiers, traders and residents. The historic Sibley cemetery, adjacent to the Fort grounds, can be accessed during your visit as well. The Santa Fe Trail can be found within a few minutes drive of the Fort.

The Fort Osage Education Center features exhibitions on the history of the Hopewell Culture, the Osage Indian Nation, Fort Osage's era of operation and the current Missouri River watershed. Access to the Missouri River is available through a hiking path from the Fort. The gift store carries a wide selection of books and merchandise related to the Fort and surrounding region.
