Mittelsteine concentration camp
Poland
The Mittelsteine concentration camp was a Nazi Arbeitslager or slave-labour camp functional on the territory of Nazi Germany during the latter part of the Second World War, now at Ścinawka Średnia in south-western Poland. It was originally established in 1942, but was operated formally for 250 days (8 months and a week) between 23 August 1944 and 30 April 1945 (the latter being the date of its liquidation) as an all-female subcamp of Gross-Rosen.
