Jefferson Barracks's Parade Ground area included a train depot built in 1902 northeast of this location that operated until passenger service ended in 1970 and was torn down by the Missouri Pacific Railroad in 1987; during the first half of the 1940s, thousands of servicemen passed through the station. A Spanish naval gun from the Spanish-American War era still stands on the Missouri National Guard base behind the Administration Building overlooking the Mississippi River. On the north side of the Parade Ground stood circa 1912 Officers Row. The Post Theater, photographed in the 1940s, is now St. Bernadette's Catholic Church. The Post Exchange and Gymnasium, now the Missouri Civil War Museum, was built in 1905 and during World War II hosted hundreds of athletic activities on the post. The area also included a trolley station, post office, and a large building at the intersection of Gregg and Hancock Roads that housed nurses who worked in the Post Hospital during World War II; beyond it stood the post office, which is no longer standing. A Jefferson Barracks trolley is shown circa 1902.
