Frontier Army Museum is a free-admission museum showcasing the history and significance of Fort Leavenworth, the oldest active post of the United States Army west of Washington, D.C. The museum is open to the public Tuesdays through Saturdays during the morning and afternoon hours, with the exception of federal holidays. 19th-century military vehicles are showcased, along with preserved weapons and equipment from the historic Frontier Army. Exhibits highlight the Army's participation in America's westward expansion, including the Lewis and Clark Expedition of 1804. Though the museum is free to enter, donations are greatly appreciated to sustain future museum operations.
