Akershus Fortress, Oslo

Akershus Fortress, Oslo (must see)

Akershus Fortress (Akershus Festning), also known as Akershus Castle (Akershus Slott), is a medieval fortification in Oslo, central to the history of Norway. The exact date of its construction is unknown but is believed to have started in the late 1290s under King Haakon V. The fortress is the namesake of the county of Akershus, which used to encompass most of Eastern Norway.

Throughout its history, Akershus Fortress has withstood numerous sieges, including those by Swedish and Danish forces between 1308 and 1532. Despite these attacks, the fortress was never captured by a foreign enemy. However, during World War II, it surrendered to Nazi Germany without a fight and later became a site for executions by the German occupiers and post-war trials. The fortress was liberated in 1945 by the Norwegian resistance.

Akershus Castle also served as a royal residence during the Middle Ages, playing a key role in the shift of Norway's capital from Bergen to Oslo. Several notable Norwegian royals, including King Haakon V, resided there. After a significant fire in 1624, King Christian IV ordered the relocation of Oslo closer to the fortress, subsequently renaming the city Christiania. The fortress was modernized into a Renaissance-style castle and continued to function primarily as a palace until the 19th century.

In addition to its military and royal functions, Akershus has also been used as a prison, holding many rebels and criminals throughout its history. Some prisoners were famous, like the notorious criminal and writer Gjest Baardsen, who served there 18 years after being given a life sentence; the legendary bank robber Ole Høiland, who committed suicide at Akershus upon his second internment; and Lars Haetta, who was sentenced to death for rebellion but was later pardoned when he began translating the Christian Bible into Sami.

Today, Akershus Fortress is still a military area but is open to the public daily. Visitors can explore the castle, the Norwegian Armed Forces Museum, and Norway's Resistance Museum. The fortress also houses the Royal Mausoleum, the final resting place for several Norwegian monarchs. The Office of the Norwegian Prime Minister is temporarily located near the fortress, and the site is still guarded by His Majesty the King’s Guard.
