In the Middle Ages, Bohus Fortress was considered one of the largest, most massive and impregnable fortresses in Northern Europe. The fortress was the southernmost border fortress in Norway, built in 1308 by the Norwegian King Håkon V. Magnusson. The fortress is located on a 40 metre high cliff on the island of Bagaholmen. At that time, Bagaholmen was surrounded by the River Göta and lay at the intersection of the three neighbouring kingdoms (Norway to the west, Sweden to the east and Denmark to the south). From the fortress there was good control over shipping on the river.
