<< Ruppichteroth Iron Age >> By Nicolas Ottersbach | January 3, 2020 | Magazine "When mining began in Ruppichteroth is no longer known exactly. But its significance for the town is known. A sign at the roundabout in Ruppichteroth, right next to the former Juliusstollen, now provides information about this. Photos: The Juliusstollen from the inside and the inauguration of the information board [Klaus Steglich] You really have to look for it, the Juliusstollen. And that's despite being located in the middle of town. Hidden by trees and greenery, beneath meters of thick rock, it burrows more than 450 meters into the mountain at the roundabout in Ruppichteroth. Anyone trying to enter it faces a locked gate. It has long been inaccessible to visitors; after a few meters, a wall and a water pump block the way. This is where the underground water streams arrive and are then pumped to the waterworks. How difficult must it have been back then to control the masses of water?..."

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!

In Marienthal, the grotto serves as a place of devotion, prayer and pilgrimage for believers from the region and beyond. Visitors come here to find solace, meditate and explore their spiritual needs. The atmosphere is often one of silence and devotion, while visitors have the opportunity to light candles and say prayers.

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.
