The Hotel Julien in Dubuque, Iowa, is described as haunted, with reports of an apparition of a man in period clothing on the upper floors, possibly the spirit of Al Capone, who frequently stayed and reportedly owned the hotel during the Prohibition era. Guests have also experienced unexplained occurrences, though specific rooms like Room 930 are not mentioned as haunted in these results. Reports mention the appearance of a man in period clothing on the hotel's upper floors. This apparition is believed by some to be Al Capone, a notorious gangster. Capone was a frequent guest at the hotel and used to rent out the entire eighth floor during the Prohibition era. Evidence suggests Capone may have even owned the hotel at one point. The hotel features an elaborately themed suite named after Al Capone, further cementing his connection to the property. Beyond the Capone sighting, the hotel's rich, storied history, including its origins in 1839 and fire in 1913, contributes to its reputation for spectral activity.
