World Heritage Convention

The General Conference of UNESCO adopted on 16 November 1972 the «Convention Concerning the Protection of the World Cultural and Natural Heritage». Today 191 State Parties have adhered to the convention.

The guiding principle of the World Heritage Convention is: «considering that parts of the cultural or natural heritage are of outstanding interest and therefore need to be preserved as part of the world heritage of mankind as a whole» (from the preamble). By signing the convention, each country pledges to conserve not only the World Heritage sites situated on its territory, but also to protect and promote its national heritage for future generations.

The Intergovernmental Committee for the Protection of the Cultural and Natural World Heritage has the final say on whether a property is inscribed on the World Heritage list. Relevant for the inscription are criteria regarding the outstanding universal value, authenticity of cultural properties or integrity of natural properties and must have an adequate protection and management system to ensure its safeguarding.

More than 1030 Cultural and Natural World Heritage sites in 163 states, distributed over all the regions of the world are included in the World Heritage list. The General Assembly to the Convention endorsed in November 2015 the resolution «World Heritage and Sustainable Development». With this resolution the State Parties are requested to enhance the sustainable development in World Heritage areas and the involvement of local communities.
