The building that now houses Chicago’s popular Excalibur Nightclub was first erected to accommodate the Chicago Historical Society after its original building was reduced to ashes in the Great Chicago Fire. When the city went up in flames in October 1871, hundreds of people sought shelter inside the historical society’s supposedly fireproof building … and many met a fiery fate. Patrons and employees of the nightclub have witnessed strange apparitions, and there have been multiple reports of people being pushed down stairs and over railings by an invisible force. In addition, one lonely candle, located high up on a wall, out of reach without a ladder, has a strange habit of lighting itself – much to the confusion of the nightclub’s employees. Party here if you dare – just make sure you watch your footing on those sinister steps.
