25. The Lemp Mansion, St. Louis, Missouri
The Lemp mansion was one of the most historic houses in St. Louis, Missouri, which was built in 1868. Four family members of the Lemp family took their own lives there after Frederick Lemp, one of the Lemp sons, died. Since then, the house had become a subject of haunted tales, reportedly by the ghosts of the Lemp family. Their ghosts reportedly appear inside the house at night.
