Mary O’Sullivan rsm (Congregation of Sisters of Mercy, Ireland) lives in the neighbourhood of the former concentration camp of Auschwitz. She ministers at the Centre for Dialogue and Prayer in Auschwitz. This Centre was established in 1992 by Cardinal Macharski in co-operation with the bishops of Europe, as well as with the representatives of Jewish organizations.

Mary serves on the Education Team at the Centre and plans programmes for groups and individuals. They offer retreats, seminars, interreligious conferences, and exhibitions, and receive guests from all over the world. They strive to help people encounter the memory of Auschwitz in a way that respects the many dimensions of its past historical reality and roots this memory in a commitment to create a civilization of love.
