World Heritage Sites are examples of artistic masterpieces and/or unique natural landscapes that are expressions of our world’s richness and diversity. Their destruction would present an irreplaceable loss to all of humanity. For this reason, the international community of states adopted in 1972 the “UNESCO Convention Concerning the Protection of the World Cultural and Natural Heritage”. Inscription on the World Heritage List represents both an honour and an obligation: the inscribed sites must be preserved in the present and for future generations in terms of their substance and their value by means of appropriate management and national-level preservation measures. Austria acceded to the World Heritage Convention in 1992 and is now represented on the World Heritage List by nine sites.
