On the fertile plains between Meknes and Rabat you’ll find the furthest outpost of the Roman Empire, the remains of Volubilis, capital of the local Roman province for two centuries from the official annexation in 40AD by Claudius. Although direct Roman rule was brief, as with other outposts of the empire, the language, culture and architecture endured for many centuries after official Roman withdrawal.
Today the site is extensive but only partially excavated. There are a number of excellent mosaics, some well-preserved villas that allow you to really imagine what they must have been like, and the largest standing structures: the Basilica, Capitol and Triumphal Arch, all typical of provincial Roman towns.
