Eighty years ago, on January 27, 1945, the Auschwitz-Birkenau concentration and extermination camp was liberated by Soviet troops. During the following weeks and months, French survivors of the camps made their way home. A third of them passed through the Hotel Lutetia in Paris, a luxury hotel that was requisitioned by the French state to host the former prisoners. Many families went to the Lutetia, desperately hoping to find out if their loved ones had returned. FRANCE 24's Stéphanie Trouillard and Claire Paccalin spoke to survivors of the camps who passed through the hotel, as well as the daughter of a man who perished in Auschwitz-Birkenau.
