After a visit to the Grande-Chartreuse in the Dauphiné, Odo, abbot of the Abbaye Saint-Remi in Reims, founded the first Carthusian monastery in France in 1132. It covered more than 12 hectares and was surrounded by a triple wall. The monastery, so close to Protestant Sedan, suffered during the religious wars, served as a prison during the French Revolution and was then partially demolished. In the open space at the foot of the Crêtes de l'Argonne there are eight sober 17th century buildings made of pink brick, with natural stone frames on doors and windows. It is all that remains of the former monastery.
