The United Nations Educational, Scientific and Cultural Organisation "seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of outstanding value to humanity... World Heritage sites belong to all the peoples of the world, irrespective of the territory on which they are located".
