The article details the extraordinary international effort to save the Abu Simbel temples in Egypt from being submerged by the creation of Lake Nasser following the construction of the Aswan High Dam in the 1960s. The temples, built by Pharaoh Ramesses II around 1265 BCE, are renowned for their colossal rock-cut statues and precise solar alignment that illuminates the sanctuary twice a year.
