The study, as part of the preparatory research of the region in the Open-air Museum of Ethnography, is a short summary of the ideas relating to a building plot from Hétfalu in Transylvania.

Along the topic of traffi c the presentation of the culture in Hétfalu is appropriate to answer recent questions such as identity preserved in a multiethnical environment or the cultural marks sustained even in a diaspora which, in our present day, can carry serious confl icts.
