Only the tabernacle, which dates back to the seventeenth or eighteenth century, is unchanged since 1815; it comes from the building allocated in 1800 to the Daughters of Charity. It was then to be found in the chapel of the Sisters of Mercy installed there before the French Revolution. Saint Catherine Labouré said that it is in front of the tabernacle that the Blessed Virgin Mary prostrated in the night of July 18 to July 19, 1830 and above it that she was during the third apparition in December 1830. In 1850 an ivory crucifix was placed on top of it.
