In these privileged natural places flows, presumably since time immemorial, a spring which, according to oral tradition, never runs dry, even in times of extreme drought.
Perhaps it had served as a baptistery for the first "colonies" of Christianity established in this region, but no document supports this hypothesis.

The same is true regarding the origin of the pilgrimage, which remains obscure.
Once again, we must refer to the legend and oral traditions dating back, it seems, to the 16th century, which reported that a hunter, having been seriously injured in the nearby forest, implored the mercy and help of the Virgin Mary.

After managing to drag himself to the spring, he dipped his panting, bloody hand into the clear water and was spontaneously healed .

Some time later, he would have returned to place an image (some even say it was a statuette) as a votive offering.

As soon as the rumor of this "miracle" spread very quickly, people from the surrounding area came in increasing numbers seeking the beneficial effects of this supposedly miraculous water for their ailments and difficulties of all kinds.

These practices persisted for a very long time and until the 1950s, the virtues of this water were especially recommended for eye conditions and pilgrims came to wash their eyes to prevent or cure diseases.
