Batn-El-Hajar
Batn-El-Hajar or Belly of Stones is a reach of approximately 160 km in length stretching from the Dal Cataract of the Nile downriver to the now under Lake Nubia submerged Second Cataract in present-day Sudan.
[1] Batn-El-Hajar is a barren and granite-rich landscape limiting arable soil and, thus, sparsely inhabited.
It was the traditional border between Upper Nubia and Lower Nubia.
In this area are a number of important A-Group[2] and Meroitics[3] archeological sites.
