Eighty years ago, on January 27, 1945, the extermination and concentration camp Auschwitz-Birkenau was liberated by the Soviets. Of the 69,000 Jews deported from France, only 5 percent survived. During World War II, the Nazis looted 100,000 items of cultural property belonging to Jewish families. After the Liberation, some 60,000 stolen works of art were repatriated to France, and 45,000 were handed back to their owners, or to family members who had survived the Holocaust. But 2,200 are still in French museums, as curators continue to search for their rightful owners. FRANCE 24's Claire Paccalin and Stéphanie Trouillard report.
