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.

This historic site is located in the heart of the Ardennes forest, surrounded by century-old trees and springs. You can explore the ruins of the monastery, which was rebuilt in the 17th century in a brick and stone style similar to that of Place Ducale in Charleville. You can also enjoy the natural beauty of the forest, where you may encounter wildlife such as deer, foxes or birds. The Chartreuse du Mont-Dieu is an ideal destination for a quiet and relaxing hike.
