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.

Waller Mill Park is a quiet spot just outside Williamsburg, built around a 360-acre lake. It’s a great place for fishing, kayaking, canoeing, or just renting a boat and getting out on the water. There are also hiking trails, picnic areas, and a dog park, making it a solid choice for a relaxing outdoor break.

Båtsmansgränd is a narrow alley located in Gamla Öster, the area above the harbour. Here, you'll find eight quaint, timber-framed boatmen's cottages, constructed in the 1740s. Their simple yet traditional design reflects the era's architectural style. Originally, they served as homes for the boatmen and their families, whom Västervik town was obliged to equip on behalf of the Crown. In the first half of the 20th century, the cottages housed members of the citizens' fire brigade. In the 1970s, these now heritage-listed cottages were converted into a hostel, available for rent in the summer.
