Oudhna is one of the oldest colonies in Africa. It dates back to the time of Augustus, who lived and ruled from 63BC to 14AD.There are still plenty of interesting buildings which are still standing and give a good idea of how the city would have looked. Within the remains of this Roman colony there is a large amphitheater dating back to the 2nd century AD; a theater and some fine Roman villas with their mosaic tiled floors still largely intact. There was also a triumphal arch, a fortress and a basilica with a circular crypt. As a civilized Roman town, it had private and public baths, an aqueduct and large water storage cisterns. The capitol is thought to be the largest in Africa, built on three levels. There are even remains of a triumphal arch, and an amphitheater.
