Changing borders and border regimes shape the lives of many people and communities, in cross-border regions these processes are even more dynamic. It may just be the case that a person can spend all their life in the same house, but at the same time, have lived in four countries. In border regions, the dominant policies and mechanisms are about contact, confrontation and transition, and at the same time these intermediate spaces also operate with their own dynamics. A view that focuses on dynamic border areas gives nuance to important processes and analyses the relationships and differences between them. Externally, the most noticeable and recognizable are those processes shaping the heritage of specific national, ethnic, linguistic, religious and other communities. In the context of Heritage in dynamic cross-border regions thematic cluster, we are interested in these diverse and dynamic practices of memory and heritage making, paying particular attention to the use of traditions and the past in constructions of borders and their margins, and their importance for self-understanding and self-representation of border communities. We take a detailed look at the possibilities and obstacles in cross-border spaces in heritagization and analyse the challenges and potential of transnational heritage-making. Namely, heritage-making enables the consolidation of dividing lines as well as the transformation of dividing border regions into meeting spaces.
