The Masonic Temple in Davenport, Iowa, is considered haunted, with paranormal investigators reporting activity in the sealed basement, including flashing lights, unexplained phenomena, and potential communication with spirits. While investigations confirm experiences like responding to questions and issues with electronic equipment, specific details about violent activity or named spirits are not detailed in these summaries, though a local legend mentions a hanged prisoner and associated eerie happenings at the adjacent, former City Hall. A significant area of paranormal interest is the building's sealed and secret basement, where a paranormal team recorded flashing lights and possible responses to their questions. Investigators have noted their night vision and infrared equipment failing to work in the Freemasons' meeting room, with some suggesting the presence of an EMP device might be responsible.
