Volubilis

Volubilis is without doubt the best preserved Roman site in Morocco. It was built around 40BC on the site of a Carthaginian settlement from the 3rd centry BC. The city was the administrative centre of the Roman province Mauretania Tingitana. Given the fertile nature of the surrounds it contributed much grain and olive oil to Rome. When the Romans left Morocco late in the 3rd century AD Volubilis was not abandoned. In fact it was still populated until it was destroyed by a large earthquake late in the fourth century AD.
Much of the marble from the site was used by Moulay Ismail for his contructions in Meknes.
Today it has some fine mosaics spread around the sprawling site.
