This museum, set in the former bailiwick prisons, showcases the history of Marchiennes and the surrounding region through a multitude of items and documents. The town grew around an Abbey built around 630 by the prominent Merovingians, Adalbaud and Rictrude. As one of the oldest and most powerful Abbeys of northern France and Belgium it exerted its influence over the local landscape until the departure of the last monks after the 1789 revolution. Vestiges of this interesting past still remain. The museum also evokes other areas of the past, from Prehistory to Modern Times, including findings from archeological excavations, the mining and glass industries of the past, the trades and games of yesteryear, the two World Wars... And there is a collection of artworks by the local artists such Loseleur, Labiss and Moral that bear witness to the artistic intensity this land has inspired over the years.
