This museum is operated by the Arizona National Guard Historical Society, a private non-profit corporation, and aims to preserve the military history of Arizona. The museums' 25 exhibits contains all varieties of artifacts including uniforms, weapons, newspapers, maps and vehicles that showcase the history of the armed forces in the state. There are displays on prisoners of war, World War I and the Arizona National Guard. The museum was founded in 1975 and is maintained by officers and directors who serve as docents, working with National Guard support to direct and upkeep the museum. The building itself is a piece of Arizona history, constructed in 1936 as a Depression-era public works project. The raw adobe building served as a National Guard arsenal until World War II at which time it was converted into a maintenance shop for German prisoners of war who were held at a nearby POW camp.
