It is indeed Chartreuse. There is also a "must-see" that presents "a magnificent view" of Chartreuse when it is actually Belledonne!!

On the occasion of the patronal feast found here—the church is dedicated to the Nativity of Mary—I would like to offer those who are here a brief impulse from Saint John of Damascus (born 675/676, died before 754) for spiritual reflection: "The day of the birth of the Mother of God is a day of universal joy, for through the Mother of God the entire human race was renewed, and the suffering of the first mother, Eve, was transformed into joy."
