The seventh installment of “Jefferson Barracks: Then & Now” is on the 1884 Mess Hall. The oldest building standing in the core of the military post, the Mess Hall was the one of first new brick buildings constructed as part of an effort to rebuild Jefferson Barracks to modern standards. The one-story building originally had arched windows, multiple entranceways, and a metal roof and served as the dining facility for soldiers stationed here. In the 1930s, alterations were made to the Mess Hall when it was converted into the main post exchange for Jefferson Barracks. In the 1990s, the building again underwent significant renovation and has since been used for offices of the Missouri Air National Guard.
