The trail around the Geisterfelsen is absolutely fantastic. Do not hesitate to make a small detour to circumvent the buttress along the blue circle. It's worth it ! 👍🤩

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 cave is located at the exit of the village of Grendelbruch and is a replica of the real cave of Lourdes. The cave used to be a quarry and it was built in the 1970s.
