Babylon Fortress (Arabic: حصن بابليون; Coptic: ⲡⲁⲃⲓⲗⲱⲛ or Ⲃⲁⲃⲩⲗⲱⲛ) was an ancient fortress in the Nile Delta, located in the area known today as Coptic Cairo. It was situated in the Heliopolite Nome, upon the east bank of the Nile, at latitude 30°N, near the commencement of the Pharaonic Canal (also called Ptolemy's Canal and Trajan's Canal), from the Nile to the Red Sea.

It was at the boundary between Lower and Middle Egypt, where the river craft paid tolls when ascending or descending the Nile. Diodorus ascribes the erection of the first fort to rebel Assyrian captives in the reign of Sesostris, and Ctesias (Persica) dates it to the time of Semiramis; but Josephus (l. c.), with greater probability, attributes its structure to some Babylonian followers of Cambyses, in 525 BC. The Romans built a new fortress nearer the river, with typically Roman red and white banded masonry.
Babylon was originally the dominant city of Mesopotamia, but another possibility links the name to the ancient Pr-Hapi-n-Iwnw (𓉐𓏤𓎛𓂝𓊪𓏭𓈘𓈖𓉺𓏌𓊖) (Nile house of Heliopolis) that was the deity Hapi's dwelling in Heliopolis city. Hapi was the divinity of the yearly inundation event of the Nile.
Heliopolis lay northeast of Memphis, on the east bank of the Nile, at latitude 30° N, and near the commencement of the Canal of the Pharaohs connecting the Nile to the Red Sea. It was the boundary town between Lower and Middle Egypt, where the river craft paid tolls when ascending or descending the Nile.
According to tradition, the first fort was built by the Persians in about the 6th century BC, but at that time it was on the cliffs near the river. When the Romans took possession of Egypt, they used the old fort for a while, recognizing its strategic importance on the Nile, but because of problems of water delivery, the Roman Emperor Trajan relocated the fort to its present location, which at that time was nearer to the river. Since then, the Nile's course has moved some 400 metres (440 yards) to the north.
Roman and Byzantine era
In the age of Augustus the Deltaic Babylon became a town of some importance, and was the headquarters of the three legions which ensured the obedience of Egypt. In the Notitia Imperii, Babylon is mentioned as the quarters of Legio XIII Gemina. (It. Anton.; Georg. Ravenn. etc.) Ruins of the town and fortress are still visible a little to the north of Fostat or Old Cairo, among which are vestiges of the Great Aqueduct mentioned by Strabo and the early Arabian topographers. (Champollion, l'Egypte, ii. p. 33.)
The town was the seat of a Christian bishopric, a suffragan of Leontopolis, the capital and metropolitan see of the Roman province of Augustamnica Secunda. The names of several of its bishops are recorded. After the Council of Chalcedon (451), some are of those who accepted the council, but most are of those who rejected it. No longer a residential bishopric, Babylon is today listed by the Catholic Church as a titular see.
During the Muslim conquest of Egypt the Byzantine fortress held out for about seven months before finally falling in December 640 to the Arab general 'Amr ibn al-'As. The history of this conquest, and of the subsequent rule of the then still Coptic Christian city by the Arabs, is told by John Bishop of Nikiû in his Chronicle, which survives now only in Ethiopic manuscripts.
