National belonging becomes problematic for minorities functioning in multinational countries, as its development is determined by multiple factors. On the one hand, such individuals identify themselves with their own cultural heritage. On the other hand, they can whether close themselves within the limits of their own culture, or quite the contrary – cross its borders, opening towards the culturally different. In the latter case, their cultural identities are of dual nature and take place in diverse spaces, specific for the cultural borderland in which these minorities function. Areas of identification, characteristic for the Polish national minority living at the Vilnius meeting point of cultures, entail public, nationally dual, and community spheres. Experiencing them results in the interpenetration of Polishness and Lithuanianness, crucial for their sense of national belonging, the formation of cultural identity, and the construction of a community at the meeting point of cultures. Moreover, such cultural experience acquired in multicultural conditions provides with an important reference for education.
