The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Cultural heritage consists of monuments (such as architectural works, monumental sculptures, or inscriptions), groups of buildings, and sites (including archaeological sites). Natural features (consisting of physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation or natural beauty, are defined as natural heritage. Italy ratified the convention on June 23, 1978.As of 2021, Italy has 58 listed sites, making it the state party with the most World Heritage Sites, just above China (56). The first site in Italy, the Rock Drawings in Valcamonica, was listed at the 3rd Session of the World Heritage Committee, held in Cairo and Luxor, Egypt, in 1979. Twenty-five Italian sites were added during the 1990s, including 10 sites added at the 21st session held in Naples in 1997. Italy has served as a member of the World Heritage Committee five times, 1978–1985, 1987–1993, 1993–1999, 1999–2001, and 2021–2025.Out of Italy’s 58 heritage sites, 53 are cultural and 5 are natural. Seven sites are transnational. The Historic Centre of Rome is shared with the Vatican; the Monte San Giorgio and Rhaetian Railway with Switzerland; the Venetian Works of Defence with Croatia and Montenegro; the Prehistoric pile dwellings around the Alps with 5 other countries; The Great Spa Towns of Europe with 6 other countries; and the Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe are shared with 17 other countries. In addition, Italy has 31 sites on the tentative list.
