Abu Simbel, Egypt
In the 1960s, Skanska worked for six years saving the 3,200-year old Abu Simbel temples in the Upper Nile. The temples, including monumental artwork of Pharaoh Ramses II and sphinxes, were moved above the rising water of a new 500-kilometer reservoir created by the Aswan Dam. The moving method, developed in Sweden, consisted of sawing the temples into 1,042 pieces. These stone blocks, weighing up to 22 tons each, were lifted and re-assembled on a plateau 64 meters above the original location.
