The first records of mining activity in the Luckenbach district date back to 1685/1686. The Edelstein brown iron ore mine runs from the tunnel entrance in the Hardt area, approximately 220 meters northwest, and was operated until around 1922, but became uneconomical. At the end of World War II, the tunnel served as an air-raid shelter. While the men were at war, the population, mothers and children, had to take refuge in the tunnel when air raid warnings sounded. Nowadays, however, only part of the mine is accessible due to overburden deposits. For safety reasons, a solid door was installed in the entrance area. From time to time, guided tours of the mine are offered, which I highly recommend.

This grotto is a replica of the famous Lourdes Grotto in France, known as the site of Marian apparitions. 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 Lourdes Grotto of Marienthal is not only a place of faith, but also a place of rest and retreat for people of all backgrounds seeking spiritual fulfillment.

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.

Former Edelstein ore mine. The former mine, whose tunnel mouth was reopened in 1991, is located in the Luckenbach district. It was apparently an underground mine operated by hand, as the first information from 1860 suggests. The ore was mined here between 1844 and 1920. The tunnel can also be visited.
