In the heart of the Nord-Pas-de-Calais region, the Gallo-Roman forum at Bavay reveals one of the largest ancient public squares in Gaul, a strategic crossroads of an empire at its height.
History
Hidden beneath the grass and black stone of Hainaut, the Gallo-Roman town of Bavay — the ancient Bagacum Nerviorum — rises from the ground with a quiet grandeur that few French archaeological sites can match. Capital of the Nervii tribe, what was once merely a tribal crossroads became, under Roman influence, one of the most well-organised cities in northern Gallia Belgica, a hub where seven Roman roads radiated out across the empire. What makes Bavay truly unique is the staggering scale of its forum: a monumental complex nearly 400 metres long, comprising an exceptionally well-preserved underground cryptoporticus whose vaulted galleries stretch for several hundred metres. These semi-underground corridors, which served both as storage areas and as weather-protected passageways, now form the archaeological heart of the site, inviting visitors to literally wander through the very bowels of a Roman town. A visit to Bavay is a gradual journey back in time: the Nord Departmental Archaeological Museum, located on the site itself, showcases thousands of excavated objects — bronzes, ceramics, coins, sculptures — which bring to life the daily life of the city in the 2nd century AD. The unique acoustics of the cryptoporticoes, the play of light filtering through the air vents, the rough texture of the limestone: every sense is engaged. The site’s contemporary setting, nestled in the small town of Bavay surrounded by hedgerows and Flemish plains, further emphasises the striking contrast between the simplicity of the present-day landscape and the former grandeur of a city that once boasted a population of up to ten thousand. A complete change of scenery just twenty kilometres from Maubeuge.
Architecture
The Bavay site is organised around a monumental forum, one of the largest identified in the northern provinces of the Roman Empire. The complex, which covers an area estimated at over four hectares, follows the classic layout of a Roman provincial forum: a large rectangular square lined with colonnaded porticoes, a civil basilica intended for judicial and commercial activities, and a temple or capitol occupying the far end of the esplanade. The rigorous symmetry of the layout betrays the ambition of a rapid and planned monumentalisation. The most spectacular and best-preserved feature is undoubtedly the cryptoporticus: a network of semi-underground barrel-vaulted galleries, built from local limestone and in opus incertum, which run beneath the forum for approximately 460 metres. These galleries, pierced by regular air vents that provide light and ventilation, maintain a constant temperature of around 10 to 12 degrees, a feature that made them ideal storage spaces and which today contributes to their striking atmosphere. The materials used reflect local resources and Roman techniques: blue stone from Hainaut, sandstone, tegulae and imbrices for the roofs of the covered buildings. Painted plaster, found in fragments during the excavations, indicates that the interiors were adorned with polychrome decorations. The columns of the porticoes, carved from limestone, were probably crowned with Doric or Corinthian capitals depending on the space. A few bases and shafts found in situ allow us to partially reconstruct the majestic silhouette that the central square presented in the heart of the 2nd century.
