Frøslevlejren was a prison camp used by the Germans in 1944, during the occupation of Denmark. Thousands of Danes were incarcerated there by the German security services. The camp changed its name after the liberation of Denmark in 1945, where it became Fårhuslejren and functioned as an internment camp for those who had collaborated with the occupying forces. Today it is an established museum where you can experience what it is like to live in a prison camp.
