to 15 years in prison for his activities at Grini. Post-war history In the immediate aftermath of Norway's liberation, Tromsdalen temporarily functioned as an internment camp for German non-military personnel. In October 1945, its name was changed to Sletta interneringsleir (Sletta internment camp). This was used to hold Norwegians convicted of treason until September 1947. In 1964, after control of the camp had been passed to Tromsøysund municipality, the barracks were demolished to make room for a secondary school. A memorial has been erected on the site of the prison camp outside what is now Tromstun skole (Tromstun school).
