On 21 April 1941, near the village of Struthof, the Nazis opened a concentration camp, KL-Natzweiler.
The central camp, the only concentration camp in France, was located in the then annexed Alsace département. Its annexes, scattered over the 2 sides of the Rhine, made up a network of nearly 70 camps, more or less large. Of the nearly 52,000 detainees of KL-Natzeiler, about 35,000 did not go through the central camp.
I was able to visit the site and memorial on a cold damp day.
