UNESCO, Egypt and Sudan have started commemorating the 50th anniversary of the Nubia Campaign, a defining example of international solidarity when countries understood the universal nature of heritage and the universal importance of its conservation.

The Egyptian and Sudanese governments' request - in April and October 1959 respectively - for UNESCO's help to save the 3,000-year-old monuments and temples of ancient Nubia from an area that was to be flooded by the Aswan Dam marked the start of unprecedented campaign.

International expertise and funds were mobilized to dismantle and reassemble six groups of monuments in new locations. The scale of the 20-year project and the immense technological challenge it generated were unprecedented in UNESCO's history. A total of 22 monuments and architectural complexes were relocated with the assistance of 40 technical missions from five continents.

The success of the Campaign inspired the development and adoption in 1972 of UNESCO's World Heritage Convention and the inscription of sites on UNESCO's World Heritage List on which the Nubian Monuments from Abu Simbel to Philae were inscribed in 1979.
