Have enemies ever captured the Akershus fortress in Norway?
The fortress has never been successfully captured by a foreign enemy. It surrendered without combat to Nazi Germany in 1940 when the Norwegian government evacuated the capital in the face of the unprovoked German assault on Denmark and Norway. http://www.nationmaster.com/encyclopedia/Akershus-fortress The fortress has successfully survived many sieges, mostly by Swedish forces, and has never been successfully captured by a foreign enemy. The Norwegians are pretty proud of that, of course. During WW II however, the fortress surrendered without combat to Nazi-Germany after the Norwegian government evacuated Oslo.
