The Virgin Mary, who is depicted and venerated here, is that of Lourdes. This well-known Marian pilgrimage site is located in the French Pyrenees and is visited by a large number of people every year, including many sick people who are hoping for a cure. The devotional image of Our Lady has become widespread - not only in France - Lourdes chapels and graves were built by believers everywhere.
The ecclesiastical commemoration day "Our Lady in Lourdes" is on February 11th, this is the anniversary of the apparition of Mary (1858), when Our Lady appeared to 14-year-old Bernadette Soubirous in a rock grotto not far from Lourdes. Bernadette later became a nun and died at the age of only 35. On December 8th (the feast of the Immaculate Conception of Mary) in 1933, she was canonized by Pope Pius XI.
The day of remembrance of the Lourdes Madonna is also World Day of the Sick.
