Chartreuse d'Aillon
Aillon-le-Jeune, France
Aillon Charterhouse, also Mont-Sainte-Marie Charterhouse (Chartreuse d'Aillon, Chartreuse Notre-Dame d'Aillon, Chartreuse de Mont-Sainte-Marie, [de] Monte Sancte-Marie de Allione), is a former Carthusian monastery, or charterhouse, located in the commune of Aillon-le-Jeune, in the Savoie department of the Auvergne-Rhône-Alpes region of France. The monastery was founded in the Bauges Mountains in the second half of the 12th century by Count Humbert III of Savoy, who provided endowments to monks likely already established at the site. The only remaining building was listed as a historic monument in 1994. Since 2008, it has housed the Heritage Center of the Bauges Massif Regional Natural Park.
