Commemoration of an expulsion can help to overcome the trauma of expelled. This is the case with the Museum of the Polish Eastern Borderland in Węgliniec, which I visited. The history of the Museum you can read and see here. It’s of course a very emotional and not professional museum, but it’s interesting to see and to listen what the whole equipment, documents and photos mean for the museum’s founder Alfred Janicki.
Janicki deals with emotions of the visitors very instrumentally. He even makes them want to cry. Unfortunatelly he also seems to own the the whole equipment, documents and photos. He works now for the city library, so hopefully the things will be later taken over by the library.
