Alton Military Prison

A shuttered prison. The Alton Military Prison was a prison located in Alton, Illinois, built in 1833 as the first state penitentiary in Illinois and closed in 1857. During the American Civil War, the prison was reopened in 1862 to accommodate the growing population of Confederate prisoners of war and ceased to be prison at the end of the war in 1865.
