The St. Louis Arsenal is a large complex of military weapons and ammunition storage buildings owned by the United States Air Force in St. Louis, Missouri. During the American Civil War, the St. Louis arsenal's contents were transferred to Illinois by Union Captain Nathaniel Lyon, an act that helped fuel tension between secessionists and those citizens loyal to the Federal government.
