On 16 November 1972, UNESCO adopted the Convention for the Protection of the World Cultural and Natural Heritage. The idea grew out of concerns about the threat of destruction of cultural and natural heritage due not only to the degradation of time but also to changing social and economic conditions. The convention, therefore, outlined what cultural and natural heritage is and how to ensure its protection.
Last November was the 50th anniversary of the World Heritage Convention in terms of resilience, humanity and innovation. The work of the past 50 years has protected and promoted the treasures of humanity and transformed the preservation of the world’s cultural and natural heritage. To date, there are 1154 World Heritage sites in 167 countries around the world.
