Benton Barracks

Benton Barracks, also known as Camp Benton, was a United States Army barracks in St. Louis, Missouri, located at present-day St. Louis Fairground Park. Before the American Civil War, the site was owned and used by the St. Louis Agricultural and Mechanical Association, which at the time was located on the outskirts of St. Louis. The installation was used primarily as a training facility for federal soldiers attached to the Western Division of the Union Army.

After the Battle of Lexington, the post and convalescent hospitals were added to the training barracks, in order to assist in treating hundreds of incoming wounded troops. Once the war ended, the barracks was dismantled, returning to its pre-war, civilian use as a fairground and race track. Nothing of the original barracks remains at this site today.
