Semna was built 35 km south of the 2nd Nile-cataract as a fortified area by Sesostris III (12. Dyn., c. 1860 BC). Thutmose III (18. Dyn, 1450 BC) added a temple honouring the nubian god Dedwen, that was disassemble in 1965 und re-erected in Sudan National Museum in Khartoum. On the opposite banks of the Nile there is the fortification of Kumma - both submerged in the Nubian Lake, part of the Nasser Lake. George A. Reisner investigated them in the late 1920s.
