The Philae temple complex is an island-based temple complex in the reservoir of the Aswan Low Dam, downstream of the Aswan Dam and Lake Nasser, Egypt. Until the International Campaign to Save the Monuments of Nubia, the temple complex was located on Philae Island, near the expansive First Cataract of the Nile in Upper Egypt. These rapids and the surrounding area have been variously flooded since the initial construction of the Aswan Low Dam in 1902. Wikipedia
