The Tranquille Sanatorium located in Kamloops, British Columbia, was initially a ranch bought in 1907 and transformed into a tuberculosis treatment center known as King Edward II Tuberculosis Sanatorium. Tuberculosis was a deadly disease known as the “white plague,” the facility was strategically placed in a secluded location, ideal for recovery with access to fresh air and a peaceful environment. On average patients would stay for about 200 days (6 and a half months), and the cost for treatment was around 55$ per month, a significant sum in the early 1900s. As medical advancements progressed, antibiotics such as streptomycin were discovered and could cure tuberculosis eliminating the need for long-term isolation. This lead to the tuberculosis facility shutting down in the year 1958. The facility remained vacant until 1959 when a psychiatric care facility was opened. Detailed records are limited in the Kamloops archive collection, the facility became a psychiatric institution, though its title during this time period remains unclear.  Throughout this transition, Tranquille continued to serve its original purpose of providing institutional care. The difference was that the focus shifted from physical health complications to mental health complications. The employees staged a 3-week protest, on account of unfair patient care. The Psychiatric facility was closed permanently in 1983. In the 1990s Tranquille served as a detention center for young men, but this did not last long as there was a $70, 000 bill owed to the B.C. government who eventually shut them down. Tranquille has lived many lives and remains an institutional landmark to those in Kamloops, as it reflects both the evolution of medical treatments and ongoing debates over institutional care for vulnerable populations.
