Reports of hauntings have long surrounded the former Pi Kappa Chi fraternity house at 723 Main Street in Davenport, which was described in 2019 as a "number-one hot spot for haunted places in the Quad Cities". However, the original building was torn down in 2020, and the fraternity has since relocated. Residents have heard heavy footsteps, disembodied typing from a typewriter, and doors opening and closing by themselves. Some former residents reported waking up at night to a feeling of being choked by an unseen entity. In 1922, when the house was still a private residence, a homeless man was reportedly brought inside to escape the cold and died in the front bedroom. An apparition of a large man wearing an overcoat has been seen entering the house and walking to the front bedroom, which is believed to be the homeless man's spirit. In the late 1970s, a psychic visiting the house claimed that the strongest spirit was a doctor. The property was previously owned by St. Luke's Hospital, which led to the theory that the doctor did not agree with the chiropractic methods being taught at Palmer College, where the fraternity was located. A mysterious blue light has been seen in both the attic and the basement of the house. While the physical building at 723 Main Street is gone, the stories of its haunted history persist in local folklore.
