This autumn, the Maison du patrimoine médiéval mosan is hosting an exhibition entitled "Histoires d'eau, un patrimoine au fil de l'eau", produced by the Service des Musées et du Patrimoine culturel de la Province de Namur. Nicknamed "blue gold", water is vital for human beings. It's just as important for healthy living, medical care and washing clothes and utensils. But water has also been used as a driving force, a defence system, a means of communication or as a means of pleasure and entertainment. Ancient beliefs have made certain springs and water sources sacred, demonstrating the importance of this resource since time immemorial. To facilitate access to water, mankind has sought to improve its supply and transport via aqueducts, water lifting machines, water towers, pumps, wells and fountains, etc.In terms of its functions and needs for mankind, the hydraulic heritage is multiple and rich. That's why it's the subject of this travelling provincial exhibition, complemented at the MPMM by a local version dedicated to the hydraulic heritage of Bouvignois and Dinant. The exhibition is open from Tuesday to Sunday, 10am-5pm.To coincide with the exhibition, a walking tour is being organised on Sunday 3 December.
