<P> In 1813 the construction of a chapel began in the Hôtel de Châtillon . On August 6, 1815 the solemn benediction of the chapel was dedicated to the Sacred Heart of Jesus . It was attributed by imperial decree to the Daughters of Charity . </P> <P> The Chapel at rue du Bac is the site of a number of apparitions said to have been experienced by Catherine Laboure . It was here on three successive days, while at prayer, Saint Vincent de Paul showed her his heart, each time in a different color . The heart appeared white, the colour of peace; then red, the colour of fire; and then black, an indication of the misfortunes that would come upon France and Paris in particular . </P> <P> Shortly after, Catherine saw Christ present in the Sacred Host, and on June 6, the 1830, feast of the Holy Trinity, Christ appeared as a crucified King, stripped of all his adornments . </P> <P> In 1830 Saint Catherine Labouré, then 24, received three visits from the Blessed Virgin Mary . On the first visit, the night of 18 July, she received a request that a Confraternity of the Children of Mary be established . Later she was to request the creation of a medal with the following invocation: "O Mary, conceived without sin, pray for us who have recourse to thee ." From May 1832 onwards the medal, which is extraordinarily disseminated and is said to convert, protect and perform miracles, is called miraculous by the faithful . </P>
