World Heritage Site

World Heritage Sites are landmarks and areas with legal protection under an international treaty administered by UNESCO for having cultural, historical, or scientific significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity".

To be selected, a World Heritage Site is nominated by its host country and determined by the UNESCO's World Heritage Committee to be a unique landmark which is geographically and historically identifiable, having a special cultural or physical significance, and to be under a sufficient system of legal protection. World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains or wilderness areas, and others.

A World Heritage Site may signify a remarkable accomplishment of humankind and serve as evidence of humanity's intellectual history on the planet, or it might be a place of great natural beauty. As of July 2025, a total of 1,248 World Heritage Sites exist across 170 countries.

The sites are intended for practical conservation for posterity, which otherwise would be subject to risk from human or animal trespassing, unmonitored, uncontrolled or unrestricted access, or threat from local administrative negligence. Sites are demarcated by UNESCO as protected zones. The World Heritage Sites list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 "states parties" that are elected by the United Nations General Assembly, and advised by reviews of international panels of experts in natural or cultural history, and education.

The Program catalogues, names, and conserves sites of outstanding cultural or natural importance to the common culture and heritage of humankind. The programme began with the Convention Concerning the Protection of the World Cultural and Natural Heritage, which was adopted by the General Conference of UNESCO on 16 November 1972. Since then, 196 states have ratified the convention, making it one of the most widely recognised international agreements and the world's most popular cultural programme.

In 1954, the government of Egypt decided to build the new Aswan High Dam, whose resulting future reservoir would eventually inundate a large stretch of the Nile valley containing cultural treasures of ancient Egypt and ancient Nubia. In 1959, the governments of Egypt and Sudan requested the United Nations Educational, Scientific and Cultural Organization (UNESCO) to assist them to protect and rescue the endangered monuments and sites.

In 1960, the Director-General of UNESCO launched the International Campaign to Save the Monuments of Nubia. This resulted in the excavation and recording of hundreds of sites, the recovery of thousands of objects, as well as the salvage and relocation to higher ground of several important temples. The most famous of these are the temple complexes of Abu Simbel and Philae. The campaign ended in 1980 and was considered a success. To thank countries which especially contributed to the campaign's success, Egypt donated four temples; the Temple of Dendur was moved to the Metropolitan Museum of Art in New York City, the Temple of Debod to the Parque del Oeste in Madrid, the Temple of Taffeh to the Rijksmuseum van Oudheden in Leiden, and the Temple of Ellesyia to Museo Egizio in Turin.

The project cost US$80 million (equivalent to $305.3 million in 2024), about $40 million of which was collected from 50 countries. The project's success led to other safeguarding campaigns, such as saving Venice and its lagoon in Italy, the ruins of Mohenjo-daro in Pakistan, and the Borobodur Temple Compounds in Indonesia. Together with the International Council on Monuments and Sites, UNESCO then initiated a draft convention to protect cultural heritage.
