The Antonius Grotto is a very well-maintained facility. It's a place created out of gratitude. Here you can also take a break in the refuge.

The Teschenhöhle is the remains of a quarry from which basalt was mined. This basalt formed a volcanic vent that formed about 43 million years ago. During the eruption, the layer of red sandstone that had not yet been removed here was broken through. You can observe this in the rock, which consists of a volcanic breccia with parts of red sandstone that was deformed by the violent eruption

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

The Teschen Cave is not a cave in the true sense, but a large hole that goes back to a quarry. So don't expect too much there! In no case (in search of the "cave") try left or straight ahead to climb up the mountain. This is extremely dangerous because slippery!
