The Illinois State Historical Society
Ruins of the first state prison in Illinois. Built in 1830-31. Unsanitary conditions aroused persistent criticism from Dorothea Dix, pioneer in prison reform. All inmates were transferred to Joliet prior to 1860. During the Civil War many Confederate prisoners were incarcerated here and deaths averaged to ten a day.
