Kom Ombo is an agricultural town in Egypt famous for the Temple of Kom Ombo. It was originally an Egyptian city called Nubt, meaning City of Gold (not to be confused with the city north of Naqada that was also called Nubt/Ombos). Nubt is also known as Nubet or Nubyt (Nbyt). It became a Greek settlement during the Greco-Roman Period. The town's location on the Nile, 50 kilometres (31 mi) north of Aswan, gave it some control over trade routes from Nubia to the Nile Valley, but its main rise to prominence came with the erection of the Temple of Kom Ombo in the 2nd century BC.

In antiquity the city was in the Thebaid, the capital of the Nomos Ombites, on the east bank of the Nile. Ombos was a garrison town under every dynasty of Egypt as well as the Ptolemaic Kingdom and Roman Egypt, and was celebrated for the magnificence of its temples and its hereditary feud with the people of Dendera.

Ombos was the first city below Aswan at which any remarkable remains of antiquity occur. The Nile, indeed, at this portion of its course, was ill-suited to a dense population in antiquity. It runs between steep and narrow banks of sandstone, and deposits but little of its fertilizing slime upon the dreary and barren shores. There are two temples at Ombos, constructed of the stone obtained from the neighboring quarries of Hagar Silsilah.

The more magnificent of two stands upon the top of a sandy hill, and appears to have been a species of Pantheon, since, according to extant inscriptions, it was dedicated to Haroeris and the other deities of the Ombite nome by the soldiers quartered there. The smaller temple to the northwest was sacred to the goddess Isis. Both, indeed, are of an imposing architecture, and still retain the brilliant colors with which their builders adorned them. However, they are from the Ptolemaic Kingdom, with the exception of a doorway of sandstone, built into a wall of brick. This was part of a temple built by Thutmose III in honor of the crocodile-headed god Sobek. The monarch is represented on tress, the doorjambs, holding the measuring reed and chisel, the emblems of construction, and in the act of dedicating the temple.

The Ptolemaic portions of the larger temple present an exception to an almost universal rule in Egyptian architecture. It has no propylon or dromos in front of it, and the portico has an uneven number of columns, in all fifteen, arranged in a triple row. Of these columns, thirteen are still erect. As there are two principal entrances, the temple would seem to be two united in one, strengthening the supposition that it was the Pantheon of the Ombite nome. On a cornice above the doorway of one of the adyta, there is a Greek inscription, recording the erection, or perhaps the restoration of the sekos by Ptolemy VI Philometor and his sister-wife Cleopatra II, 180-145 BCE. The hill on which the Ombite temples stand has been considerably excavated at its base by the river, which here strongly inclines to the Arabian bank.

The crocodile was held in especial honor by the people of Ombos; and in the adjacent catacombs are occasionally found mummies of the sacred animal. Juvenal, in his 15th satire, has given a lively description of a fight, of which he was an eye-witness, between the Ombitae and the inhabitants of Dendera, who were hunters of the crocodile. On this occasion the men of Ombos had the worst of it; and one of their number, having stumbled in his flight, was caught and eaten by the Denderites. The satirist, however, has represented Ombos as nearer to Dendera than it actually is, these towns, in fact, being nearly 100 miles (160 km) from each other. The Roman coins of the Ombite nome exhibit the crocodile and the effigy of the crocodile-headed god Sobek.

In Kom Ombo there is a rare engraved image of what is thought to be the first representation of medical instruments for performing surgery, including scalpels, curettes, forceps, dilator, scissors and medicine bottles dating from the days of Roman Egypt.

At this site there is another Nilometer used to measure the level of the river waters. On the opposite side of the Nile was a suburb of Ombos, called Contra-Ombos.

The city was a bishopric before the Muslim conquest, and under the name Ombi is included in the Catholic Church's list of titular sees. Karol WojtyÅ‚a (the future Pope John Paul II) was titular bishop of Ombi from 1958 until 1963, when he was appointed Archbishop of Kraków.

Temple of Kom Ombo:

It is an unusual double temple in the town of Kom Ombo in Aswan Governorate, Upper Egypt. It was constructed during the Ptolemaic dynasty, 180–47 BC.Some additions to it were later made during the Roman period.

The building is unique because its 'double' design meant that there were courts, halls, sanctuaries and rooms duplicated for two sets of gods. The southern half of the temple was dedicated to the crocodile god Sobek, god of fertility and creator of the world with Hathor and Khonsu. Meanwhile, the northern part of the temple was dedicated to the falcon god Haroeris ("Horus the Elder"), along "with Tasenetnofret (the Good Sister, a special form of Hathor or Tefnet/Tefnut) and Panebtawy (Lord of the Two Lands)." The temple is atypical because everything is perfectly symmetrical along the main axis.

The texts and reliefs in the temple refer to cultic liturgies which were similar to those from that time period. The temple itself had a specific theology. The characters invoked the gods of Kom Ombo and their legend. Two themes were present in this temple: the Universalist theme and the local theme. The two combine to form the theology of this temple. A temple was already built in the New Kingdom to honor these gods, however, this site gained in importance during the Ptolemaic Kingdom. Little remains of the New Kingdom temple. The existing temple was begun by Ptolemy VI Philometor (180–145 BC) at the beginning of his reign and added to by other Ptolemies, most notably Ptolemy XIII Theos Philopator (51–47 BC), who built the inner and outer hypostyles. The scene on the inner face of the rear wall of the temple is of particular interest, and "probably represents a set of surgical instruments."

Much of the temple has been destroyed by the Nile, earthquakes, and later builders who used its stones for other projects. Some of the reliefs inside were defaced by Copts, who once used the temple as a church. All the temples buildings in the southern part of the plateau were cleared of debris and restored by Jacques de Morgan in 1893.

Crocodile Museum:

A few of the three hundred crocodile mummies discovered in the vicinity are displayed in The Crocodile Museum.

Near the Ptolemaic gateway on the southeast corner of the complex is a small shrine to Hathor, while a small mammisi (birth house) stands in the southwest corner. Beyond this to the north you will find the deep well that supplied the temple with water, and close by is a small pool in which crocodiles, Sobek’s sacred animal, were raised.

The path out of the complex leads to the new Crocodile Museum. It's well worth a visit for its beautiful collection of mummified crocodiles and ancient carvings, which is well lit and well explained. The museum is also dark and air-conditioned, which can be a blessing on a hot day.

In April 2018, the Egyptian Ministry of Antiquities announced the discovery of the head of the bust of Roman Emperor Marcus Aurelius during work to protect the site from groundwater.

In September 2018, the Egyptian antiquities ministry announced that a sandstone sphinx statue had been discovered at the temple. The statue, measuring approximately 28 cm (11 in) in width and 38 cm (15 in) in height, likely dates to the Ptolemaic Dynasty.
