Porte de Mars

The Porte de Mars stands as the most significant remnant of Durocortorum, the Gallo-Roman city that preceded modern-day Reims. During the Roman era, Durocortorum was the capital of the province of Gallia Belgica and one of the most populous cities north of Rome. The arch was constructed in the 3rd century AD as a grand monumental gate, celebrating the peace and prosperity brought by the Roman Empire. Its name derives from a nearby temple dedicated to Mars, the Roman god of war. The structure is remarkable not only for its immense size—being the widest known arch in the Roman world—but also for its detailed interior soffits, which feature intricate carvings of a local harvesting calendar and mythological scenes, including Jupiter and Leda.

Interestingly, the survival of the Porte de Mars is largely due to its incorporation into the medieval castle of the Archbishops of Reims. When the castle was eventually demolished in the 16th century, the arch was rediscovered and left standing. Today, it serves as a majestic focal point in the Hautes Promenades, a recently revitalized park area that blends the city's ancient heritage with modern urban landscaping. The site provides a tangible connection to antiquity, offering visitors a quiet space to reflect on the layers of history that have shaped the Champagne region over millennia.

Reasons to Visit

• It is the widest triumphal arch in the entire Roman world, offering a unique glimpse into ancient architectural scale.

Things to Avoid
