Located on Kamloops Lake in British Columbia, Canada, Tranquille Sanatorium began its life as a ranch before the owners began caring for tuberculosis patients. It was converted to a full hospital in 1907, specifically meant to treat victims of TB. After treating more than 4,000 patients over the years, it closed in the 1950’s and wild rumors began to surface that, at the time of its closing, there was no sign of patients or staff, though that has been more or less proven to be false.
It would eventually reopen, primarily serving as a hospital and training facility, but then shut its doors for good in 1985. You may actually recognize it from several movies, including the recent version of The A-Team, as well as several television shows. Over the years, there have been reports of mysterious floating orbs throughout the facility, inexplicable feelings of sadness, unease and sudden drops in temperature. There have also been reports of mysterious voices and spectral figures, including that of a nurse who was allegedly murdered by a patient.
