Reviews Summary

Visitors consistently praise Oscarsborg Fortress for its rich WWII history and stunning natural beauty. The free access to the grounds and the impressive artillery emplacements are major highlights, offering a tangible connection to the past. While the museum is noted as being a bit dated, the overall experience is highly recommended for its historical significance and scenic location.

"Great experience. I travelled independently whereas most people seem to go as part of a tour. Had a chat with a couple of friendly guides who were most informative and justly proud of the brave Norwegian garrison who sank the German cruiser Blucher. Good museum within the fort itself and no restrictions on access to the Fort guns which defended Oslo so well in April 1940. There is also a hotel on the island again with friendly staff. Highly recommended."

JOHN APPLEBY

"Deep history, stunning views.
My deep respect to colonel Erikson for his courage and bravery in 1940. Sad that the museum looks as if it is stuck in time. At that, the fact that the fortress is free to enter is an important indicator that the museum regards keeping the memory as its main task"

Oksana Chelysheva

"Historic 19th century island fortress, famous for the sinking of the German heavy cruiser Blucher. Set in a very beaufitul location in Oslofjord, accessible by ferry. Interesting museum, including a video display of the fateful sinking, with a display of heavy artillery pieces in their emplacements around the grounds. Nice island to stroll around and enjoy the fantastic views."
