Natzweiler-Struthof was a German-run concentration camp located in the Vosges Mountains close to the Alsatian village of Natzwiller (German Natzweiler) in France, and the town of Schirmeck, about 50 km (31 m) southwest of the city of Strasbourg. Natzweiler-Struthof was the only concentration camp established by the Nazis on French territory, though there were French-run temporary camps such as the one at Drancy. The camp was located in a heavily-forested and isolated area at an elevation of 800 metres (2,600 ft).
