The Missouri Civil War Museum is a fully recognized 501(c)(3) not-for-profit educational organization. Our organization was incorporated in 2002 for the sole purpose of saving the historic Jefferson Barracks 1905 Post Exchange Building and converting it into what will become Missouri’s largest and finest Civil War museum, library, and educational center. Since our opening in June 2013, we have become one of the largest Civil War Museums in the nation and will be one of the largest Civil War research libraries in the nation as well. Our focus is entirely on Missouri’s role in the American Civil War.

Our facility is located within the Jefferson Barracks Historic Site in St. Louis, Missouri, which is recognized as the oldest active military installation west of the Mississippi River. The Jefferson Barracks National Cemetery was established during the American Civil War (1863) and is the final resting place for some 16,000 Civil War soldiers from both the Union and the Confederacy. Many people believe that Jefferson Barracks is without question, one of the most sacred and historically significant sites in all of Missouri regarding the American Civil War. The brave Civil War soldiers who served here, died here, and are now at rest here have made it so.
