632 N. Dearborn St, River North
The former Chicago Historical Society building -- better known as “Excalibur” to most party-friendly Chicagoans -- has long had a reputation for being one of the most haunted buildings in the city. For decades, employees claim to have witnessed a wide variety of supernatural activity: dozens of candles being re-lit or extinguished, wine taps turning on by themselves, bottles suddenly breaking, and even apparitions of a man in a tuxedo, a woman in red, and a little girl.
Visitors have reportedly heard children crying, describe feeling a “heavy” energy and have difficulty breathing when in the Dome Room, the building’s paranormal hot spot. While filming an episode of Ghost Adventures, one cast member even felt he may have been pushed down the stairs by an unseen force. While there have been plenty of rumors surrounding the source of the paranormal activity -- the most common one being that the building was used as a temporary morgue after the Eastland Disaster -- most are either false or are difficult to prove simply because they pre-date the Chicago fire. Which, you know, burned down the original building and (allegedly) everyone who took shelter inside of the “fireproof” building who now (supposedly) haunt the place.
