Reinterpreting (national) intangible heritage: how do we present ourselves?

When Croatia became a member state of the European Union in 2013, a huge public ceremony was organized on the main square in Zagreb. The artistic director compiled a program primarily "for a domestic audience and then for the Others." Intangible heritage was the salutary backbone for the program. A year earlier, a co-author for the celebration of the Statehood Day in Slovenia advocated for public emancipation of "folklore activities." How do we present ourselves nowadays? Are we now in the new age of reinterpreting our national identities in the European Union? How is cultural heritage used in construction of local and national identities and, at the same time, serve as the best way for promotion of cultural diversity and intercultural dialogue?
