The Waverly Hills Sanatorium was opened in 1910 to house patients suffering from Tuberculosis. Before the advent of antibiotics, this deadly disease claimed the lives of 50% of its victims. This meant that tens of thousands of people breathed their last in this gothic building, making it one of the most haunted sites in America. Brace yourself for The UnBelievable with Dan Aykroyd.
