A visitor takes a picture with a smartphone of a furnace in a crematorium building of the former Natzweiler concentration camp, put in place by the Nazis amid World War II, also called "Struthof", in Natzwiller, eastern France, on November 12, 2024. To mark the 80th anniversary of the liberation of Alsace, French President Emmanuel Macron is preparing to pay his respects at Natzwiller, in the Bas-Rhin department. At an altitude of 800 metres in the foothills of the Vosges mountains, Natzwiller was the site of the only concentration camp in France, in Alsace, which was annexed by Nazi Germany at the time.
