View over Elephantine Island, looking northeast, showing the desert beyond and the imposing fortifications of the Monastery of St. Simeon at upper left; Aswan is an Egyptian city at the northern end of the first Nile cataract, about 900 km south of Cairo. The modern town chiefly stretches along the eastern bank of a sandstone valley, which also contains numerous islands formed by the granite outcrops of the cataract; its ancient monuments are found on both the east and west banks and on some of the islands.
