Western Hainaut

Western Hainaut is the name of the North-West part of the Province of Hainaut ( Hainaut occidental in French) . Since the creation of an autonomous Wallonia, it is also called Wallonie Picarde, in light of the regional use of the Picard language.

Geography

The most important city in Wallonie picarde is Tournai which is also the oldest city of the Low countries. The Tournai Cathedral, has been classified both as a Wallonia's major heritage and as a World Heritage Site.Tournai is labelled on Tabula Peutingeriana. Tournai gives its name to the Tournaisian: The “Calcaire de Tournai” comprises the limestone formations cropping out in the Mélantois-Tournaisis Anticline (...) which have been quarried since the Roman conquest. Its relationship with the succession of the Dinant area was only understood following study of the Asile d’Aliénés borehole at Tournai and the Vieux-Leuze borehole at Leuze [...] These boreholes exhibited a rather typical middle Tournaisian succession below the “Calcaire de Tournai” that was easy to correlate with the succession of the Dinant area.
