The project “Meeting after Years” of the Museum of the Łęczna-Włodawa Lake District is an opportunity to acquaint the European society unique testimonies of the tragic events of World War II. The product is a unique archival and documentary package for the European education system and materials for international conferences, meetings and debates. Furthermore, the results of the project were used as the academic background for the first European temporary exhibition “From the Ashes of Sobibór”. This even was a special kind of summary of the hitherto collaboration of the Sobibór Museum with those states whose citizens had been murdered in the extermination camp. The authors of the project hope that its results will help foster those relations and enrich the European awareness of the responsibility for Sobibór remembrance
