Kungelf Bohus ruin.

Unknown

The fortress began to be built in 1308 by the Norwegian King Håkon V Magnusson in order to rein the nearby Ragnhildsholm stronghold, which the Swedish Duke Erik Magnusson had his violence. The house, which was originally wooden, soon became one of Norway’s most important places by limiting the river Göta Älv, and by increasingly powerful fortifications of stone, also one of the strongest castles in the whole of Norway. Bagaholm - the islet on which the fort was located - was the district court of Viken’s court judge and the High White Man on Bohus had ruled only over the south and later the north of the landscape, which after bail was named Bohus County. The fortress was used from 1308-1678. Controlled by Norway, Denmark - Norway, Sweden Source: Wikipedia. Bohus Fortress.
