Ruins (BAVAY)

The hypocaust is an ancient system of underfloor heating that was used by the Romans and Gallo-Romans, mainly to heat their baths (hammams). The Bavay Hypocaust, in a cellar of the rue Saint-Maur, dates back to the 1st century AD. It was discovered by the Canon Henry Biévelet in 1953 and bears witness to the strategic positioning of Bavay as the ancient capital of the Nervians (Nervii) and an important urban centre of Belgian Gaul.
