Passageway through the Ampitheatre at El-Jem

Taken from: http://en.wikipedia.org/wiki/El_Jem

The city was built, like almost all Roman settlements in Tunisia, on former Punic settlements. In a less arid climate than today's, Roman Thysdrus prospered especially in the 2nd century, when it became an important centre of olive oil manufacturing for export. It was the seat of a Christian bishop - which is still occupied by a titular Roman Catholic bishop today.

By the early 3rd Century AD, when the amphitheatre was built, Thysdrus rivalled Hadrumetum (modern Sousse) as the second city of Roman North Africa, after Carthage. However, following the abortive revolt that began there in 238 AD, and Gordian I's suicide in his villa near Carthage, Roman troops loyal to the Emperor Maximinus Thrax destroyed the city. It never really recovered.

How thorough the destruction was in the 3rd century is not known. Perhaps there was a garbage dump at Thysdrus like the one at Oxyrhyncus.

El Djem is famous for its amphitheatre, capable of seating 35,000 spectators. Only Rome's Colosseum (about 45,000 spectators) and the ruined theatre of Capua are larger. The amphitheatre at El Djem was built by the Romans under proconsul Gordian, who was acclaimed Emperor at Thysdrus, around 238 and was probably mainly used for gladiator shows and chariot races (like in Ben-Hur). It is also possible that construction of the amphitheatre was never finished.

Until the 17th century it remained more or less whole. From then on its stones were used for building the nearby village of El Djem and transported to the Great Mosque in Kairouan, and at a tense moment during struggles with the Ottomans, the Turks used cannons to flush rebels out of the amphitheatre.

The ruins of the amphitheatre were declared a World Heritage Site in 1979.
