Let’s leave the trappings of the temporal behind and treat ourselves to a spiritual retreat. We’ll walk from shell to shell on the Way of Saint James, all the way to Lourdes. From Alençon to Chartres, passing through Nevers and Paray-le-Monial, we’ll visit France’s sanctuary cities. In Rocamadour, we’ll climb the 216 steps to genuflect before the Black Madonna. We’ll round things up at Mont-Saint-Michel at Via Aeterna, it’s festival of holy music.
