Aim: The family home, as a place of significance for the younger generation, plays a key part in the process of creating their identity. Family is the first environment of the experience for a child and also the cultural one. It is thanks to its culture-generating role that the child becomes a part of the culture of its own family (nurtured and developed from generation to generation), the national culture, the general social or the community cultures that the family members are part of. Thus, a unique cultural space is created where the child gathers experiences, getting to know the specificity of a given culture and then makes choices, so that finally the cultural self-identification can take place during the process of shaping its own identity. Such cultural identifications are multidimensional in the cultural borderland, as these reflections have proved. The aim of this study was to define the specificity of the cultural experiences of the younger generation of Poles in the Vilnius cultural borderland, in particular regarding their cultural identifications in the family environment. Methods: The research exploration concerning the above outlined issues was carried out with the application of the method of diagnostic survey. Results: The research embraced 106 teenagers coming from Polish families, and living in the Vilnius region. Relying on the conclusions from our own research, carried out amongst the young generation of Poles living in the Vilnius area, a conceptualisation of the cultural space of the family in a borderland took place, followed by the distinction of its primary dimensions, i.e. the inheritede, the pre-existent, and the accomplished. With reference to each of the latter the author described generating factors that are of key importance in the process of the cultural identification of the younger generation functioning in the cultural borderland. On such grounds the conclusions tackled not only the cultural orientations of the researched, but equally their cultural capital with regards to the process of establishing a community in the multicultural environment. For the latter, the culture of the borderland has proved to function as a point of reference, entailing cross-cultural and cross-national features.
