The water cave is located a little off the path. A small stream still flows from it today, which once supplied the castle with water.

The Mother of God depicted and venerated here is that of Lourdes. This well-known Marian pilgrimage site is located in the French Pyrenees and is visited by many people every year, including many sick people hoping for healing. The devotional image of the Mother of God has become widespread - not only in France - and Lourdes chapels and grottos have been built by believers everywhere. The ecclesiastical memorial day "Our Lady in Lourdes" is February 11th, this is the anniversary of the Apparition of the Virgin Mary (1858), when Our Lady appeared to 14-year-old Bernadette Soubirous in a rock grotto very close to Lourdes. Bernadette later became a nun and died at the age of just 35. She was canonized by Pope Pius XI on December 8, 1933 (the Feast of the Immaculate Conception of Mary). The Day of the Lourdes Madonna is also World Day of the Sick.
