"Medieval Fortress Fun Take the bus to Kungälv and walk up to Bohus Fortress (Bohus Fästning), which has guarded the northern entrance to Gothenburg at the Nordre River since 1308. During the summer lots of medieval-style activities take place, like sword fighting, archery, and “knight school” for children. Don’t go back to Gothenburg until you have taken a walk along Västra gatan, a charming street with old wooden houses. Maybe stop for fika , too."
