Origin and history

The archaeological site of the Marais, located in Chambly and extending over the neighbouring commune of Belle-Eglise, is an exceptional vestige of an almost uninterrupted occupation between the Gallo-Roman period and the Carolingian period. The excavations revealed an active Gallo-Roman villa from the 1st to the 4th century AD, as well as traces of a habitat and a hydraulic mill dated from the 10th century. The latter, from the Carolingian period, is considered a unique example in France, highlighting the technical ingenuity of this period.

The Gallo-Roman villa illustrates the importance of rural settlements in the Roman Gaul, while the mill, connected by a road to the Carolingian habitat, attests to a structured economic and social organization. The occupation of Carolingian habitat was precisely dated between 930 and 980 thanks to dendrochronology, providing a rare time frame for this period. The site, protected since 1997, is thus a material testimony of the transitions between late Antiquity and the Middle Ages.

Ranked a Historic Monument, the site of the Marais includes various remains (habitat, mill, villa) that reflect architectural changes and lifestyles over nearly a millennium. Its listing of historic monuments in 1997 underscores its heritage value, although its exact location remains approximate (estimated at 5/10). The protected elements cover several cadastral plots, confirming the extent and complexity of this major archaeological site.
