Ombos is the Greek name of a city of the ancient Egypt, called Nubt by the Egyptians. It is also the site predynastic of Naqada which delivered many tombs and a funerary movable rich person of this period.

It would seem that before even the reunification of the two grounds, Seth, the god of High-Egypt, its principal worship would have had there. The Delta saw the triad Osirienne, Aset (Isis), Ausare (Osiris) and Horus-the-Young person, to become extensive. Assassin of its brother Ausare, Seth did not resist the late times where the Egyptians banished it of the Pantheon, leaving room to Horus-l' Ancien (Haroëris) and Sobek. The superb ptolémaïque temple of these two divinities makes today think of an acropolis, southernmost in the area of Assouan to Kôm Ombo than it is thus advisable not to confuse with Ombos.

Naqada, ancient city of times predynastic, occupied the south of the site and extended over a length of more than one half-kilometer. This site forms one of the rare urban whole of this period which arrived to us. The necropoles were next to the city. The site continued to be inhabited with the Ancient Empire, then seems to be erased to reappear more in north with Nubt.

Indeed, the site seems to be re-occupied at the end of the second intermediate period within sight of the discovered tombs with Ballas, site close to Nubt. It is in Ballas also that Reisner discovered at the beginning of the 20th dating century two raw brick enclosures from the which at least one a palate contained. Undoubtedly this site represents the advanced base of the sovereigns in fight against the Hyksôs and Nubt formed its pertaining to worship center then nearest.

It is there that the vestiges of the temple of Seth were discovered. The unit was excavated by Petrie and Quibell at the end of the 19th century and goes back essentially to the Nouvel Empire. They thus revealed that the temple followed a East-West axis and was locked up in a raw brick enclosure of an about sixty meters length open to the east and the west by two pylons also out of raw bricks. The majority of the found blocks go back from and in particular to Thoutmôsis {{Ier}}. The Musée of Cairo thus has a lintel of door in the name of this Pharaon where one can see the god Seth facing the name of Horus of the king and tightening the signs of life to him.

A deposit of foundation in the name of Thoutmôsis {{III}} shows that the temple was even altered increased by the famous conquering Pharaon. However the plan of the sanctuary is not easily identifiable so much this part of the temple was levelled contrary to the additional parts which comprised stores and attics.

The temple occupied the center of the town of then and the site seems to have been occupied until the {{intermediate IIIe}} period.

The site comprises necropoles being spread out predynastic period with its burials characteristic of the first times at the end of the New Empire. With the Ancient Empire of the Mastaba S were built for the local elite, while the king, undoubtedly Snéfrou of, built a small pyramid with degrees as it did it in Seila or on the island of Éléphantine to Assouan.
