Oscarsborg Fortress, Oslo

(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.

  • There are excellent and some very interesting displays that tell,the story of Nirway's history through the defense of the city. We didn't allow enough time. We should have spent half a day there. 
  • Had the pleasure of being with the premiere of the King's view on No in the courtyard. Really a wonderful experience, with a spectacular end. Somewhat cold.. One should perhaps considered terrassevarmere on selected place.. A bit poorly planned with sound on the deal before the view. Before the movie we were invited on a private tour of the torpedo battery. It was very exciting. I dishes a thank you to the former officer who took us with Oscarsborg is a place we are going to visit several times.

  • Beautiful ancient fortress, it was built when Norway was not an independent State. Solid construction of the stone blocks, performed military functions for a long time, and in the last century was used as the location of a military base. It is interesting to walk inside the fortress, excellent landscapes from above. Recommend

  • 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.
