Villers Abbey was founded in 1146 by the Cistercians. With the presence of slate and rich silt soil, all the conditions were present to found an abbey in this area. The domain surrounding the historical heritage is 30 hectares in size and houses eight gardens with different themes, a historical mill and a monk's pharmacy. Exhibitions, concerts and shows are regularly held on the site. If there is nothing to do, you can still settle down in the bistro to taste the abbey's beer.
