In 1972 Unesco created the World Heritage Convention linking together the concepts of nature conservation and the preservation of cultural heritage. Based on the understanding that sites and monuments are threatened with deterioration or disappearance over time, the organization determines that those of outstanding universal value deserve special protection from the dangers they are facing. Therefore, the efforts to identify, protect, preserve, and value the sites included on this list are meant to safeguard and pass the world's cultural and natural heritage on to future generations.
Overall, to be included on the Unesco World Heritage List, sites must be of outstanding universal value and meet at least one out of ten selection criteria created by the organization. According to Unesco, a site has outstanding universal value when it has cultural and/or natural importance that transcends national boundaries and is therefore of great relevance to current and future generations of mankind as a whole.
The criteria are regularly revised by the World Heritage Committee to reflect the evolution of the World Heritage concept itself. The list is also constantly updated with new sites, separated into categories: cultural heritage, natural heritage, and mixed heritage.
Cultural Heritage
The following shall be considered as cultural heritage: monuments such as architectural works, sculpture, painting, elements or structures of an archaeological nature, inscriptions, cave dwellings; groups of buildings which are of outstanding universal value from the point of view of history, art or science; and sites by works of man or the combined works of nature and man, which are of outstanding universal value from the historical, aesthetic, ethnological or anthropological point of view.
