Sanctuary of Our Lady of Lourdes

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 administered 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".
