France, Pas-de-Calais, Neuville-sous-Montreuil, The Chartreuse Notre-Dame-des-Prés is a monastery founded in 1325 for the Carthusian Order by the Count of Boulogne near Montreuil-sur-mer... In its 700-year history, the Chartreuse has been destroyed, rebuilt, used as a hospital, a cultural centre, occupied by monks, then by nuns... Now riddled with merula, the Carthusian monastery is second only to Notre-Dame de Paris in terms of restoration work.
