This article questions notions of belonging in the case of displaced communities’ descendants and discusses such groups’ efforts to preserve their heritage. It examines the instrumental use of nostalgia in heritage discourses that drive preservation efforts. The case study presented is focused on the Russian Old Believers in Romania. Their creativity in reforming heritage practices is considered in relation to heritage discourses that emphasise continuity. The ethnographic data presented in this article, derived from my doctoral research project, is focused on three major themes: language preservation, the singing tradition and the use of heritage for touristic purposes.
