Consecrated in 1833, this church served as the seat for the first German national assembly in 1848, which in turn provided the basis for Germany’s present-day constitution. Today, the site hosts award presentations as well political and cultural events.

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.

Welcome to the Nordic region's longest narrow-gauge railway between Hultsfred and Västervik. Smalspåret is a living museum showcasing the railway journey some 40–50 years ago. In the summer, both steam trains and railbuses roll along the tracks, with booked tours for groups available year-round. Designated by the Swedish National Heritage Board as one of the country's most interesting industrial monuments, the railway traverses scenic landscapes, alongside lakes and past steep mountains.
