Waverly Hills Sanatorium

The original Waverly Hills Sanatorium, a two-story wooden structure, was opened in 1910, but the larger brick and concrete structure as it stand today was completed in 1926. The hospital was always dedicated to the treatment of tuberculosis patients, a disease that was fairly common in the early 20th Century.

It is estimated that as many as 63,000 people died as the sanatorium. Those deaths coupled with the reports of severe mistreatment of patients and highly questionable experiments and procedures are ingredients for a haunted location.

Ghost investigators who have ventured into Waverly have reported a host of strange paranormal phenomena, including voices of unknown origin, isolated cold spots and unexplained shadows. Screams have been heard echoing in its now abandoned hallways, and fleeting apparitions have been encountered.
