Kumma (Nubia)
Kumma or Semna East is an archaeological site in Sudan. Established in the mid-12th Dynasty of Egypt, it served as a fortress of ancient Egypt in Nubia. Along with Semna, Kumma was built by the Pharaoh Sesostris III. The forts protected the border between ancient Egypt and the southern areas.
Kumma is situated about south of Aswan, and southwest of the second cataract of the Nile on the eastern bank. Semna is located on the other side. Both locations are flooded today because of the Aswan High Dam on Lake Nubia. The salvaged temple of Khnum is rebuilt in the National Museum of Sudan at Khartoum.
