In ancient Egyptian times, Kulb was the southernmost point for metal miners who searched for copper ore and gold for the
Pharaohs. During the
4th and
5th Dynasties of Egypt, the Ancient Egyptians
quarried from the northern
Wadi Allaqi large amounts of copper, leaving rock inscriptions naming Kulb by two officials, "Overseer of the metal detector" (LMY-r smntyw) and a "scribe of the metal detector" (SŠ smntyw). They were apparently responsible for the collection of gold, as their titles indicate that the search for raw materials in Nubia was organized as a state enterprise. From the Roman period, the granite mountains of the Batn-El-Hajar separated the area culturally from the Egyptian influenced
Upper Nubia. Kulubnarti has been inhabited since about 1100 AD. It was used until the end of the Christian kingdom of Makuria as a retreat for Christians in Nubia. A fortress on the island may have existed even before that time. ==Excavations==
