Despite the built breakwaters, this settlement in Nubia did not last forever. According to researchers, around a thousand years BC, the dry climate of the region created very unfavorable conditions. Around 200 years BC, the flooding of the river probably stopped forever in some areas, the breakwaters were destroyed and the others drowned.
For example, we can point to the examples that researchers discovered near the ancient temple of Suleb on the west bank of the Nile. These structures, whose length reaches 700 meters, are made of stone slabs weighing 100 kg per piece.
The walls, unlike river breakwaters found on dry land, were connected directly or hooked to active river channels, creating a deep, calm channel that facilitated boat access, much like a modern dock or wharf.
More research is needed for the correct dating of these structures; But considering the 3,000-year-old breakwaters that have been discovered around, it is possible that these structures are just as old.
According to Dalton, what surprised him is that these huge breakwaters helped connect ancient Egypt and Nubia by facilitating the movement of resources, armies, people and ideas across the long distances between the upper and lower Nile. He finds it surprising that the importance of this topic has been ignored until today.
