Akershus Fortress is a medieval castle situated in Oslo city centre. Throughout its history it has had great strategic and symbolic value for Oslo and Norway. Akershus Fortress is still a military area, but it is open daily to the public until 21.00

The building of Akershus Castle and Fortress commenced in the late 1290s under King Haakon V. The medieval castle, which was completed in the 14th century, had a strategic location at the very tip of the headland, and withstood a number of sieges throughout the ages, primarily by Swedish forces. Its immediate proximity to the sea was very important as naval power was vital in protecting the interests of Norwegian commerce, which was largely carried out by sea during the period.

The castle was modernised under King Christian IV (1588-1648) and converted into a Renaissance castle and royal residence. During the 17th and 18th centuries, the castle fell into disrepair and restoration work did not start until 1899.
