Both established and improvised jails and prisons throughout the country were also used for internment by the Nazi authorities.
In particular the Sicherheitspolizei and Sicherheitsdienst, headquartered at Victoria Terrasse, were notorious for torture and abuse of prisoners.
Also, Arkivet in Kristiansand and Bandeklosteret in Trondheim became synonymous[citation needed] with torture and abuse.
It is estimated that between 38,000 and 40,000 individuals passed through this camp system, for a total of 60,000 prisoner years.
Effectively every local prison was used for these purposes by the Nazis, but several full-fledged camps were also established.
