Deeply marked by the Holocaust, Poland occupies a central place in European collective memory. Preserving the memory of this tragedy in the present while passing on the lessons to future generations is a complex challenge. This dissertation focuses on three main areas: firstly, the history and challenges of commemoration in Poland, where remembrance duty and policies intersect; secondly, the challenges of remembrance museums in response to tourist income and the erasure of remembrance sites; and finally, the role of visitors, confronted with museum content likely to cause upset or emotional shock. This journey to the heart of Polish memory questions how to commemorate without distorting history.
