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!

Nice tunnel, you can go in about 20 m. Don't forget the light.

The tunnel leads reasonably straight into the mountain. You should pay attention to your own head, as there is only 1.70m headroom and occasional sharp slate peaks protrude from the ceiling.
