Västervik's hospital, opened in 1912, was established due to the acute need for psychiatric care facilities. The hospital functioned as a self-contained community, housing approximately 1,400 patients and 900 staff at its peak. It was a closed world, now revealed at the Psychiatric Museum. The museum is housed in a former ward restored to its original condition. Visitors can take a guided tour to learn about the care practices during the hospital's operational days. The museum also features photographs from that era. In addition to the permanent exhibition, there are several smaller events organized each year.
