World Heritage Site [SEP] Origin
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 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 appeal 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.
