Chapelle Notre-Dame-de-la-Médaille-Miraculeuse

On the rue du Bac in the 7th arrondissement, this chapel is one of the most visited pilgrimage sites in Paris, drawing millions each year. It marks the place where, according to Catholic tradition, a young nun reported visions of the Virgin Mary in 1830, leading to the striking of the famous Miraculous Medal. The bright interior enshrines the relics of the visionary and the seat where the apparitions were said to occur. Despite its fame, the chapel is tucked discreetly behind a courtyard off a busy shopping street.
