Chicago is one of the most haunted cities in the world, boasting a colorful but disturbingly dark and violent past. Many of the sites on our tours are notorious for their ghost sighitngs and paranormal activity. Others are not as well known. The stories behind many of these hauntings range from the truly chilling to the light- of heart. We've found that some spirits of our beloved but haunted Chicago seem to beg loudly for recognition and remembrance, while others remind us of their reality in a more subtle fashion. We think a few wish to teach lessons, while others remain playful. All, we believe, wish not to be forgotten.
