The ruins of Volubilis near Meknes, a Roman settlement constructed on what was probably a Carthaginian city, dating from 3rd century BC. Volubilis was a central administrative city for this part of Roman Africa, responsible for the grain and olive oil producing in this fertile region, and exports to Rome. Volubilis was also administering contacts with the Berber tribes which the Romans never managed to suppress, but who only came as far as to cooperate with the Romans for mutual benefits.
