Chapel of Our Lady of the Miraculous Medal

The Chapel of Graces of the Miraculous Virgin or informally the Chapel of Our Lady of the Miraculous Medal, is a Marian shrine located in Paris, France.

Originally constructed via the imperial decree of King Louis XVIII on 25 March 1813, the chapel was formerly within the former building of Hotel de Châtillon. It was blessed and dedicated to the Sacred Heart of Jesus on 6 August 1815 and served as a part of the motherhouse of the Order of the Daughters of Charity of Saint Vincent de Paul.The famed address of the shrine is #140 — Rue du Bac, Paris, France. The chapel is reputed to be where the Blessed Virgin Mary is said to have appeared to a novice of the Daughters of Charity, Catherine Labouré, in December 1830 and requested the creation of the medal of the Immaculate Conception that came to be known as the Miraculous Medal by popular demand.
