The paper focuses on the question whether the former Polish-German border along the Piaśnica River in Northern Kashubia is also a ‘long-term-duration’ border. The old border, although no longer on the political map after 1945, still exists in the collective memory of the inhabitants of the former borderland. The ‘phantom border’ is tangible in material memorials and in language use. A particular case is the social memory of the inhabitants of the village Nadole, which was a Polish enclave on the German side of Lake Żarnowieckie between 1920-1939. The paper presents results of research on this memory conducted through text analysis of historical sources and ethnographic interviews with the local people. A local myth of the ‘hero’s journey’ plays an important role for the construction of the social memory of Nadole. Various Kashubian political activists can be cast as the hero. Until today the memory of the interwar period has been the basis of the image of ‘Us’ and ‘the Others’.
