The Sanctuary of Our Lady of Lourdes or the Domain is an area of ground surrounding the Catholic shrine to Our Lady of Lourdes in the town of Lourdes, France. The Sanctuary is a destination for pilgrimage; sick pilgrims are reputed to be miraculously healed by Lourdes water. This ground is owned and administrated by the Roman Catholic Church, and has several functions, including devotional activities, offices, and accommodation for sick pilgrims and their helpers. The Domain includes the Grotto itself, the nearby taps which dispense the Lourdes water, and the offices of the Lourdes Medical Bureau, as well as several churches and basilicas. It comprises an area of 51 hectares, and includes 22 separate places of worship. There are six official languages of the Sanctuary: French, English, Italian, Spanish, Dutch and German.Grottos intended as replicas of the one at Our Lady of Lourdes, and other grottos in honour of Our Lady of Lourdes, are often described as "Lourdes grottos".HistoryBeginning on 11 February 1858, a 14-year-old peasant girl named Bernadette Soubirous claimed to have experienced a series of apparitions of a girl dressed in white and with a blue belt around her waist, who eventually introduced herself as the Immaculate Conception, a name by which the Virgin Mary was known.On land bordered by a loop of the Gave de Pau river is an outcrop of rock called Massabielle, (from masse vieille: "old mass"). On the northern aspect of this rock, near the river bank, is a naturally occurring, irregularly shaped shallow cave or grotto, in which the apparitions took place.
