During the first centuries of its existencen the castle had four towers connected by high perpendicular walls, and within the walls were dwellinghouses, storehouses etc. The tower with the entrance to the castle-yard was a gate-tower with four storeys above the arachway, called the Kings's Hall.
The history tells of a great number of personages, kings and queens and other celebrities, who had their namens connected with the castle. It was here that queen Blanche of Namur celebrated her marriage to king Magnus Eriksson of Sweden and Norway. Here her daughter in law, queen Margaret of the united countires of the North, received king Albrekt of Mecklenburg, former king of Seden, but defeated by Margarets armies. Here he had to atone for the insult he had offered her by calling her king Lack-hose and other still more infamous appellations.
The catle has endured no less than fourteen sieges, but it has never been carried by assault. In the 17th Century the castle of Bohus was abondoned and destroyd, and it is only during the last eleven decades that the Swedish governement subsidizes a progressive restoration, with a view to preserving the imposing ruin from further destruction.
