Illinois's mysterious and often violent history has made the state a haven for restless spirits.

Hauntings are believed to be created from violence and bloodshed. And from the beginning, the Prairie State was a place where death thrived, and mysteries became commonplace. Illinois was the home of ancient peoples know as Moundbuilders whose only legacy is silent graves and many unsolved mysteries. The French left behind their own ghostly stories after their displacement by the Americans in the 1700s and countless slaughters such as the Dearborn Massacre gave birth to tales of horror that live on in the history of Illinois. Eerie occurrences, spooky events, unsolved mysteries, and terrifying specters haunt Illinois. Tales of headless horsemen, haunted castles and a penitentiary occupied by ghosts chill the spines of visitors. Haunted Illinois explores the Prairie State's paranormal side and serves as a guide to its haunted places.
