It became notorious for housing Confederate prisoners of war, with over 11,000 soldiers confined within its walls before the prison's closure.\n\nDorothea Dix, a prominent figure in prison reform, recognized the dire need for improvement in the prison's oversight and conditions. Her criticism sparked significant reforms within Illinois' correctional system, ultimately leading to the construction of a more humane prison in Joliet, Illinois, which opened its doors in 1858.\n\nDespite the prison's closure and subsequent demolition in the early 1870s, a pair of walls stand as a poignant memorial to Alton's role in the Civil War and the broader movement towards social justice.",
