Nubia

The area to the south of Kom Ombo until the Sisal Mountains in the south of the Nile valley is basically known as Nubia, Nubia is divided into two parts:

Upper Nubia which is part of Sudan now, and lower Nubia which the most southern part of Egypt and ends up in to Wadi Halfa

It was in our modern time that attention was given to this part of Egypt since the construction of the Aswan first dam and then flowed by the Aswan high dam, ever since that time the eyes of the Egyptologists over the world turned to this site.
