Decumanus Maximus and Arch of Caracalla

The Decumanus Maximus and Arch zone forms one of the most memorable routes through Volubilis. The Decumanus Maximus was the principal east-west street of the Roman city, lined with important houses and urban infrastructure, and it still gives visitors a clear sense of the ancient street plan. Walking along this route leads to the Arch of Caracalla, also known as the Arch of Triumph, one of the site’s most distinctive monuments. The arch was erected between December 216 and April 217 C.E. by the council of Volubilis in honour of Emperor Caracalla, who granted Roman citizenship to the inhabitants. Today it stands as a powerful visual anchor, marking the meeting point of important sectors of the city and offering one of the classic photographic views of the ruins. The surrounding area reveals the structure of Roman urban life more clearly than almost anywhere else on the site, with broad paving, building remains, and sightlines across the open countryside. This zone is ideal for travelers who want to understand how Volubilis was organized as a city rather than simply as a set of monuments. It is also one of the best places to appreciate the frontier character of the settlement, where Roman architecture was set within a fertile Moroccan landscape.
