There are 32 World Heritage Sites in India that are recognised by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as of 2014. These are places of importance of cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. The Convention concerning the protection of the World Cultural and Natural Heritage was adopted on 17 November 1997 following the General Conference of the UNESCO held from 17 October 1972 to 21 November 1972. India’s first two sites inscribed on the list at the Seventh Session of the World Heritage held in 1983 were the Agra Fort and the Ajanta Caves. Over the years, 30 more sites have been inscribed, the latest being the Great Himalayan National Park in 2014. Of these 32 sites, 25 are cultural sites and the other seven are natural sites. A tentative list of further sites/properties submitted by India for recognition includes 51 sites. The cultural sites in India are marked by their brilliant craftsmanship on stone. Most of the temples of India which are inscribed on this list are built in stone, without any mortar and with sculpture carved on it.
