The exhibition “Forgiveness and Reconciliation; Cardinal Kominek, an Unrecognized Father of Europe” presents the  figure of Boleslaw Kominek, archbishop of Wroclaw, the author of the letter sent in 1965 by Polish bishops to their German counterparts containing the famous sentence We forgive and ask for forgiveness, and therefore one of the promoters of Polish-German reconciliation and as such one of the Fathers of Europe. For there can be no doubt that without the Polish-German  reconciliation which paved the way towards recognition by the Federal Republic of Germany of Poland’s western frontier on the  Oder-Neisse line, the eastward enlargement of the European Union would have been jeopardised in not rendered completely impossible.
