Zbigniew Niziński visited an elementary school with integrated classes in Warsaw and there carried out a lecture and presentation about his trips following the traces of the common history of Poles and Jews. The students were told the stories from the times of war about the Jews who had survived the Holocaust as well as the Poles with the title of the Righteous Among the Nations of the World. The children also became acquainted with preserved monuments of the Jewish culture as well as with searching for and commemorating the burial sites of the people murdered during the war.
