The grotto was inaugurated in 1954. Until the end of the 1960s, a procession to the grotto took place every year on May 1st and August 15th. Beautifully designed and inviting place. There is more information about the history on the board on site. Definitely worth a visit!

The devotional image of the Mother of God, as passed down by the visionary Bernadette, has found widespread popular piety - not only in France - and Lourdes chapels and grottos have been built by believers everywhere.
