World Heritage Sites are the historically and culturally important places that are listed by UNESCO as sites of cultural or physical importance. ‘World Heritage Committee’ of UNESCO manages the list of World Heritage Sites. To identify, protect and conserve the cultural and natural heritage across the globe, the United Nations Educational, Scientific and Cultural Organization (UNESCO) begins this. In the Protection of the World Cultural and Natural Heritage Convention, a global treaty, signed in 1972 by UNESCO, the Heritage list was started. Total 38 world heritage sites are in India which 30 are of Cultural importance, and 7 of Nature and 1 is of mixed importance.

Conclusion:

World Heritage Sites are the historically and culturally important places that are listed by UNESCO as the sites of cultural or physical importance. It is very important to preserve the natural and manmade heritage of the world and India. The government of India, along with UNESCO must protect these sites and the other 100’s sites of India. India presently has 38 world heritage sites in which 30 are of Cultural importance, 7 of Nature, and 1 is of mixed importance. Sites such as the Taj Mahal, Kaziranga national park, and others get protection and get international recognition, which also boosts tourism in India.
