Bohus fortress

The medieval fortress at the town of Kungälv, Sweden

Bohus Fästning (“The fortress of Bohus”, originally Bagahus) is situated at the former Swedish / Norwegian border. It was Haakon V Magnuson, the king of Norway (between 1299-1319) who gave the construction order. He also initiated the construction of Akershus in Oslo, Norway. At this time, Bohuslän (where Kungälv is situated), belonged to Norway.

Bohus fortress was invested 14 times and badly damaged, but not once taken. At one point, the border was moved north and the fortress was to no-use to Sweden anymore. Then the norweigans built Fredriksten fortress.
