Cross-cultural heritage proves to be a key case exemplifying the emergence of a “New Heritage”. Our emerging understanding of Third Culture Kids’ (TCK) cross-cultural heritage is an understanding of one particular community of people and their place in the world. In addition, cross-cultural heritage also exemplifies the possibilities and challenges of community participation in heritage management. This chapter presents a better understanding of how members of the community of former TCKs, adults, identify and give meaning to cultural heritage. Cultural heritage no longer has the ability to provide territorially-defined nation-states with distinctive identities and narratives for their citizens to feel a sense of unity. In a world increasingly affected by migration, mobility, dislocations, and multicultural values, it is not only valuable but ethically necessary to explore which alternative forms of cultural heritage may be more suitable and appropriate to the TCK heritage community.
