Volubilis is an archaeological site in Morocco situated near Meknes and features the best preserved Roman ruins in this part of northern Africa.
In antiquity, Volubilis was an important Roman town situated near the westernmost border of Roman conquests.
The Romans began building the city of Volubilis ca. 40 AD in order to keep control of this north African region which was successively occupied by the Greeks, Berbers, Jews and Carthaginian merchants.
The Triumphal Arch facing the main route was built in 217, in honour of the Roman emperor Caracalla. It formerly had a bronze chariot atop its ancient stones. It was restored in 1962.

In 1997 the site was listed as a UNESCO World Heritage site.
