The amphitheatre is built of stone blocks, located on a flat ground, and is exceptionally well conserved. The amphitheatre of El Jem is the third amphitheatre built on the same place. The belief is that it was constructed by the local proconsul Gordian, who became the emperor as Gordian III.
From left to right: Temple of Minerva is in the best condition, while the Temple of Jupiter next to it has almost all of its walls still standing. The Temple of Juno has fared worse, but there is plenty to help you imagine what it must have looked in pristine condition. To the south of the forum is the Arch of Antionius Pius.
The southernmost of the three temples was dedicated to Minerva, which was the daughter of the two gods revered in the other two temples. She was considered to be the virgin goddess of warriors, poetry, medicine, wisdom, commerce, crafts and inventor of music. Her temple appears as the most impressive of the three from the outside, and even the interior is in excellent condition.
The Temple of Jupiter stands in the middle, being the temple of the most important of all gods in the Roman pantheon. It is the largest temple, and deduced from its present, excellent condition, it was the object of first-class engineering. It is noteworthy that the temple has no entrance by itself, it was entered by bridges across arches from either of the other two temples.
The Temple of Juno is by far the least impressive of the three making up the Capitol. It is also the most ruined one. Juno was the Queen of the gods, the wife of Jupiter and the mother of Minerva. The niche in the middle had a statue of the goddess, which has never been found.
The arch is leading into the open courtyard of the Forum with its three openings ans was built on 139 according to an inscription on the entrance archway. It is clearly among the finest arches of any site in Tunisia, and adds a dramatic effect to the arrival to the Forum. Note that it was never finished, to which the rough surface of the four columns in front testifies.
