Volubilis is a partly excavated Berber city in Morocco situated near the city of Meknes, and commonly considered as the ancient capital of the kingdom of Mauretania. Built in a fertile agricultural area, it developed from the 3rd century BC onward as a Berber, then proto-Carthaginian, settlement before being the capital of the kingdom of Mauretania. It grew rapidly under Roman rule from the 1st century AD onward and expanded to cover about 42 hectares with a 2.6 km circuit of walls. The city gained a number of major public buildings in the 2nd century, including a basilica, temple and triumphal arch. Its prosperity, which was derived principally from olive growing, prompted the construction of many fine town-houses with large mosaic floors.
The city fell to local tribes around 285 and was never retaken by Rome because of its remoteness and indefensibility on the south-western border of the Roman Empire.
