Old Ordnance Room

Free admission. ($3 Suggested Donation)

The exhibit entitled Courageous and Faithful; The Cavalry at Jefferson Barracks (sponsored by Emerson) ran from March 7, 2015 - May 30, 2016. The American Association for State and Local History (AASLH) recently announced that St. Louis County Parks is the recipient of an Award of Merit for this exhibit!  
The AASLH Leadership in History Awards, now in its 71st year, is the most prestigious recognition for achievement in the preservation and interpretation of state and local history. The exhibit's purpose was to educate visitors on the birth of the United States Cavalry at Jefferson Barracks, and its purpose, which was to conquer the American Frontier. The men who joined became the vanguard of westward expansion. The exhibit explored the contributions of the mounted troops at Jefferson Barracks, and the role they played in bringing about the settlement of the western half of the nation.
