Germany has agreed to contribute $80m (£51m; 60m euros) towards a fund aiming to preserve the Auschwitz Nazi death camp as a symbol of the Holocaust.
The Auschwitz-Birkenau Fund, set up in 2009, says $120m is needed to preserve the site in southern Poland.
The barracks, gas chambers and other buildings that are part of the memorial are in need of urgent repair.
More than a million people were murdered by the Nazis at Auschwitz.
"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 on Wednesday.
