(4.6/5 based on 170+ reviews on the web)
Oscarsborg Fortress is a coastal fortress in the Oslofjord, close to the small town of Drøbak. The best known part is situated on two small islets. The main artillery batteries are on the island Håøya and smaller batteries on the mainland to the west and east in the fjord and was military territory until 2003 when it was made a publicly available resort island. The fortress is best known for sinking the German heavy cruiser Blücher on 9 April 1940.In 2014, Oscarsborg Fortress was given protected status, effective from 9 April that year.Early historyThe narrows at Drøbak, called Drøbaksundet, is a natural point for the naval defence of Oslo, the capital of Norway. The first defences were constructed during the reign of Christian IV of Denmark and Norway and were ready in 1644. The fortifications were however not involved in battle during the Hannibal War.After the war the fortifications were dismantled, and only resurrected for a short period during the 1814 war with Sweden.Around 1830 the discussion started for a renewed fortification of the Drøbak Narrows and the first stage was ready in 1848, the next in 1853. The name of the fortress was given by royal resolution on 23 August 1855 after a visit by the Swedish-Norwegian King Oscar I.

  • Nice and interesting place to visit. A walk around the fortress and the island gives a good understanding of the dramatical first hours of Germanys occupation of Norway during WW2.  more »
  • Great port to add with your own boat. Well depths. A stroll on the island is a great experience. A lot of history here! Easy to take the ferry boat to Drøbak/in town.

  • Here comes the one really in close contact with a very important part of Norway's military history (World War II). One wanders on historical reason and can get interesting information, and enjoy the wonderful surroundings.

  • So Madam Butterfly in outdoor life, very nice experience and fine surroundings of the fortress. Boat transport could have been better, but understandable because of the production.
