Grini Detention Camp
A women's prison never used for its intended purpose — Norway's occupation turned it into a Nazi concentration camp the day the walls went up.

From June 1941 to May 1945, SS and Gestapo personnel ran Grini for Norwegian political prisoners, Soviet POWs captured during Operation Barbarossa, and common criminals. Of the 19,247 people who passed through, 3,402 were shipped onward to camps inside Germany. In 1942, teachers who defied the Nazi-backed union were held here for a single day before being transported to Kirkenes.
What to look for
- The original 1938 women's prison structure, finished in 1940 but never used as planned before the occupation repurposed it
- The 1942 barracks addition, built to expand capacity as prisoner numbers outgrew the original building
- The naming anomaly: the camp took the name 'Grini' from a nearby farm to the southeast — the actual site sits in the Ilen area, which had no historical connection to that farm
Ila Detention and Security Prison now operates on the same grounds in Bærum; confirm public access before visiting, as it remains an active correctional facility.
