Damanhur, chief town of the Governorate of Buhayra, which extends from the Rosetta arm of the Nile to the Western (Libyan) Desert, lies on the Mahmudiya Canal at the west end of the Delta. It was the ancient Egyptian Behdet, later known as Time-en-Hor ("City of Horus"), from which its present name derives. In Roman times it was named Hermopolis
Parva and was capital of the 15th nome of Lower Egypt.
Damanhur is now an important railroad junction, with several cotton ginning plants. It is also the market town of the very fertile surrounding area and a major center of the rice trade. There are no remains of the ancient city.
