World Heritage Site 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 a number of important temples, the most famous of which are the temple complexes of Abu Simbel and Philae. The campaign, which ended in 1980, was considered a success. As tokens of its gratitude to 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,
Abu Simbel temples as a lasting monument to the king and his queen Nefertari, and commemorate his victory at the Battle of Kadesh. Their huge external rock relief figures have become iconic. The complex was relocated in its entirety in 1968 under the supervision of a Polish archaeologist, Kazimierz Michałowski, on an artificial hill made from a domed structure, high above the Aswan High Dam reservoir. The relocation of the temples was necessary or they would have been submerged during the creation of Lake Nasser, the massive artificial water reservoir formed after the building of the Aswan High Dam on the Nile River.
