Renaissance and Denmark-Norway

In 1449-1450 the castle was besieged again, this time by the Swedish king Karl Knutsson Bonde, but he had to lift the siege after a while. The castle was not besieged again until 1502 when Scottish soldiers in the service of the Danish king besieged the castle in order to regain it from the hands of the Norwegian nobleman Knut Alvsson. Akershus was besieged yet again in 1523, this time by Swedish soldiers but Oslo’s inhabitants, at the command of Hans Mule, burned down their houses in an attempt to drive them out and the Swedes retreated after a short period. King Christian II besieged the castle from 1531 to 1532 but the siege was lifted by forces from Denmark and Lübeck. After this siege the castle was improved and strengthened. In 1567, during the

Several significant figures from the Norwegian middle ages, including Haakon IV, Queen Euphemia, Ingeborg Eriksdottir and Queen Margaret, all resided at the castle, which functioned as the official Norwegian royal residence for several decades.

Prison

Akershus has also been a prison, with a section of it known as ''The Slavery'' ( no, Slaveriet) because the prisoners could be rented out for work in the city. It has housed many rebels and criminals through Norwegian history. Particularly well-known people to have been imprisoned there include author Gjest Baardsen (1791–1849), and the similarly idealized thief Ole Høiland. Also, many early Norwegian
