Västervik is an old harbour- and trading town with mostly traditional wooden buildings. Worth a particular mention are two rows of boatswains cottages from the middle of the 18th century. In the centre of town is the fishing harbour where the town fishermen used to sell their catch. Every year in the middle of July Hasselörodden (archipelago festival with rowing contest) takes place to commemorate this trade. In S:t Gertrud's church from the 15th century there are two votive ships, both from the 18th century. Right next to the harbour are the ruins of Stegeholm fortress, which in late medieval times controlled the approach to the narrow Gamleby bay.
