The Polish authorities in charge of Auschwitz have launched an official site for the former Nazi death camp on the social networking website Facebook.
A spokesman said the move was aimed at reaching the younger generation and educating them about the Holocaust.
It follows the launch by Auschwitz – now a state museum – of a YouTube channel earlier this year.
More than a million people – 90% of them Jews – were murdered by the Nazis at Auschwitz during World War II.
