Pope Francis will visit the Auschwitz-Birkenau concentration camp in July.
He will visit the former Nazi death camp in southern Poland on July 29, on the third day of his visit to the country.
Two of his predecessors have also visited the camp, John Paul II – himself Polish – in 1979 and retired pope Benedict XVI in 2006.
1.1 million people, including a million Jews from across Europe, were killed by Nazi Germany at the camp from 1940 to 1945.
The other victims were mostly non-Jewish Poles, gypsies and Soviet prisoners.
