WARSAW, Poland — Germany pledged Wednesday to pay euro 60 million ($80 million) over the next year into a fund for Auschwitz-Birkenau to preserve the barracks, gas chambers and other evidence of Nazi crimes at the former death camp, some of which are deteriorating to the point of collapse. Germany is the largest of several countries contributing to the Auschwitz-Birkenau Fund, which was set up in 2009 to gather money to maintain the 472-acre expanse made up of the original camp, Auschwitz, the nearby satellite camp of Birkenau. The camp was operated by Nazi Germany in occupied Poland during World War II. More than 1 million people, mostly Jews, died in the camp’s gas chambers or through forced labor, disease or starvation. “Germany acknowledges its historic responsibility to keep the memory of the Holocaust alive and to pass it on to future generations,” German Foreign Minister Guido Westerwelle said in a statement. “Auschwitz-Birkenau is synonymous with the crimes of the Nazis. Today’s memorial recalls these crimes.”
