Here is the mouth of the former ore mine tunnel "Pauline". The mine was in operation from 1871 - 1809. Today the tunnel serves as a home for local bats and is a reminder of times gone by - well done!

The Mother of God depicted and venerated here is the one from 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 who hope 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 church memorial day "Our Lady of Lourdes" is on February 11th, this is the anniversary of the Marian apparition (1858), when the Mother of God 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. On December 8th (the Feast of the Immaculate Conception of Mary) 1933, she was canonized by Pope Pius XI. The commemoration of the Madonna of Lourdes is also World Day of the Sick.
