Philae is an island in the reservoir of the Aswan Low Dam, downstream of the Aswan Dam and Lake Nasser, Egypt. Philae was originally located near the expansive First Cataract of the Nile in Upper Egypt and was the site of an Egyptian temple complex. These rapids and the surrounding area have been variously flooded since the initial construction of the Aswan Low Dam in 1902.The temple complex was dismantled and moved to nearby Agilkia Island as part of the UNESCO Nubia Campaign project, protecting this and other complexes before the 1970 completion of the Aswan High Dam. The hieroglyphic reliefs of the temple complex are being studied and published by the Philae Temple Text Project of the Austrian Academy of Sciences, Vienna (Institute OREA).

The Aswan Dam benefits Egypt by controlling the annual floods on the Nile River and prevents the damage which used to occur along the floodplain. The Aswan High Dam provides about half of Egypt's power supply and has improved navigation along the river by keeping the water flow consistent
