The Tell el-Balamoun was excavated from 2003 until 2010 by a British team led by Jeffrey Spencer. There, they found a Roman street and various ancient temples, including a temple of Amun of Ramses period and a sacred boat of the 26th dynasty, with mentions of the pharaohs Shoshenq IV and Takeloth. Shoshenq IV describes himself as « son of Bast », « Master of Heliopolis ». More complete inscriptions evoke « the lord of Sma Behedet, the Great God, Lord of Heaven » and « Amon-Re, Lord of Sma Behedet ».
Archaeologists inferred that the ancient city represented by the Tell el-Balamoun, was created around 2400 BC, and was called Séma-Behedet originally meaning "Behedet of the North ". Towards the end of the New Kingdom it would have changed its name to that of Paiuenamun, which means "Island of Amun", which gave the today name of Balamoun.
This same city was designated Diospolis Parva during the Ptolemaic period.
Sema-Behedet is confirmed as a city of the extreme north of the kingdom in registrations designating Egypt by "from Sema-Behedet to Elephantine".
It is also possible that the two names have remained during the same period time: one specifically designating the sacred boat, the other the temple of Amun.
