The Ghostly Alton Ruins: A Peek into History's Haunted Hallways

Nestled in the charming town of Alton, Illinois, you'll come across the ghostly Alton Military Prison, which began life as the state's inaugural penitentiary in 1833. However, this place has a ghostly history, hosting an ever-growing throng of Confederate prisoners of war during the American Civil War. By 1865, it had transformed into a place that gave off more chills than thrills, a veritable mausoleum of misery. Nowadays, a placid wander would reveal a fragment of the wall that's been preserved, bearing a plaque from the state of Illinois and recognized on the National Register of Historic Places.
