Museums have gradually come to act in part as society’s memory, and through their educational efforts they contribute to the sustainable development of the world. The conference “The National Museums in a Globalised World” address the question of national museums through international dialogue and exemplifies how the museum world has become internationalised. Modern Museums are global players in the cultural sector and cross-cultural cooperation is of growing importance.
