The Pope has offered a private prayer at the former Auschwitz death camp.
Pope Francis walked alone and in silence around the concentration and extermination camp in what was Nazi-occupied Poland where 1.1 million people, mostly Jews, were killed.
The Pope also met elderly survivors of the camp, kissing them on the cheeks and speaking to them softly.
He is on his third day of a visit marking 1,050 years since Poland’s adoption of Christianity.
Francis has become the third Pope to walk through the main gate of Auschwitz, under its infamous inscription “work sets you free”.
