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

The chapel of the Daughters of Charity in the rue du Bac was blessed on 6 August 1815. There, between July and December 1830, the Virgin appeared three times to a young novice, Catherine Labouré; the medal she described, inscribed «Ô Marie conçue sans péché», was first distributed in 1832. The chapel was remodeled for the centenary of the apparitions in 1930, and Catherine Labouré was canonized by Pius XII in 1947. A frame from a video of 16 September 2025, taken during Mass, looks toward the apse.
