Waverly Hills Sanatorium, opened in 1910 in Louisville, Kentucky, was initially a tuberculosis hospital, renowned for its advanced treatments and open-air design. After closing in 1961, it gained notoriety for alleged paranormal activity, attracting ghost hunters and enthusiasts. Reports of ghostly apparitions, eerie sounds, and unexplained phenomena have fueled its haunted reputation. While stories of hauntings are popular, they lack scientific confirmation and often rely on anecdotal accounts.
