Korosko was a settlement on the Nile River in Egyptian Nubia. It was located south of Aswan and served as the point of departure for caravans avoiding the Dongola bend in the river by striking out directly across the desert to Abu Hamad and thereby bypassing the second, third and fourth cataracts of the Nile. The "Korosko route" or "Korosoko road" was in use during the period of the New Kingdom (1550–1077 BC), when Pharaohs Thutmose I and Thutmose III marked it with boundary stelae. During the Meroitic period it was the main connection between the Kingdom of Kush and the Mediterranean world.
