The temples of Abu Simbel were relocated due to the construction of what?
Abu Simbel are two massive rock-cut temples in Upper Egypt near the border with Sudan. In the 1960s, construction on the nearby Aswan High Dam was set to completely submerge the location upon its completion, so an enormous relocation project was undertaken. The relics, statues, and buildings of the ancient site, dating to the 13th century BCE, were all moved onto an artificial hill above the newly formed reservoir.
