The Belen Harvey House Museum is rumored to be haunted by the spirits of former Harvey Girls and passengers, with reports of unexplained lights, sounds of talking and laughing, and sightings of a Victorian-dressed woman. The building's basement is considered a particularly active and dreaded location where unexplained occurrences are said to happen. People have reported seeing lights turn on and off in the building, even when they were thought to be off. Some individuals, including a former mayor, have reported hearing disembodied voices, such as two women talking and laughing, only to find no one present when investigating. There are stories of staff and visitors encountering a woman in a black Victorian dress with her hair pulled back in a bun. The building's basement is considered a notorious area for paranormal activity. Some believe the spirits of former Harvey Girls, the female waitresses who worked and often lived in the building, may have never left.
