A 14 year shepherd girl named Bernadette Soubirous reported seeing Mary appear to her while she was out gathering firewood in the countryside. Mary identified herself as "the Immaculate Conception" and told Bernadette of the location of a spring, promising miraculous healings from its waters. Since 1862, over sixty medical cures associated with Lourdes have been certified as "miraculous" by the Catholic Church, which established its own Medical Bureau in 1883 to review and evaluate claims of cures. The Apparitions was approved in January 18, 1862.

Accompanied by her sister and a friend, Bernadette went to Massabielle on the banks of the Gave to collect bones and dead wood. Removing her socks in order to cross the stream, she heard a noise like a gust of wind, she looked up towards the Grotto : “I saw a lady dressed in white, she wore a white dress, and equally white veils, a blue belt and a yellow rose on each foot.” Bernadette made the Sign of the Cross and said the Rosary with the lady. When the prayer ended the Lady suddenly vanished.

Bernadette felt an inner force drawing her to the Grotto in spite of the fact that she was forbidden to go there by her parents. At her insistence, her mother allowed her; after the first decade of the Rosary, she saw the same lady appearing. She sprinkled holy water at her. The lady smiled and bent her head. When the Rosary ended she disappeared.
