Part of the historic Oscarsborg Fortress, Oscarsborg Castle inhabits a small island located south of the Norwegian capital city. The island itself is specifically situated within a narrow waterway known as the Drøbak Sound (Drøbaksundet), which has been used as a natural defensive point against foreign naval incursions for hundreds of years. During the second World War, the fortress played a significant role at the Battle of Drøbak, when six German warships attempted to attack Oslo at the start of the Norwegian Campaign during the Second World War. As the fleet made its way toward the Oscarsborg Fortress amid the early morning hours of April 9, 1940, the fort’s commanding officer gave the order to launch a surprise bombardment. Not only had the Oscarsborg Fortress sunk one of Germany’s most prized ships, it had also bought precious time for the Norwegian Royal Family to evacuate the area. But despite its great success in delaying the invasion, the fort fell to the Axis powers the following day.

After spending the rest of the conflict under German occupation, the Oscarsborg Fortress resumed protecting Oslo from hostile ships once the war had ended. The last military facility to operate on the island was the Coastal Artillery Office Training Program, which officially closed down in 2002. Instead of falling into a state of decay, the site quickly emerged as a popular cultural attraction. People from the across the world began flocking to the fortress in great numbers, prompting the conversion of a section of the complex into the current Oscarsborg Castle. The Norwegian Directorate of Cultural Heritage even registered the entire location as one of its protected heritage landmarks in 2014.

Today, both the Oscarsborg Fortress and Oscarsborg Castle are among Norway’s most fantastic holiday destinations. The 89 guestrooms offer a peaceful environment, perfect for unwinding after a day of exploring the island. A selection of the rooms also offer stunning views of the Oslo Fjord.
