November 6, 2025, Lourdes Grotto Rohren

The Lourdes Grotto was built in 1903 on the initiative of Father Hesseler, the parish priest of Rohren. It is an expression of the deep piety and trust in God of the people. Even today, the grotto is a destination for pilgrims who implore the Virgin Mary for help in times of need.

Nowadays, a sign hangs on the (closed) gate: "Trou d'homme de la conduite Reinhardstein". So it is about a tunnel to/escape route from the nearby castle.

Situated in the quieter part of the valley. The higher paths are more frequented, rockier and more adventurous than this part. Definitely worth a visit!

On a hot summer day you can cool off here - the refrigerator effect near the tunnel is impressive!

It is quite possible that this old slate tunnel serves as a quarters for bats in winter.

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 believers have built Lourdes chapels and grottos everywhere. The church's memorial day for "Our Lady of Lourdes" is February 11th, 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.

This grotto was built by the inhabitants in recognition of the protection of the Holy Virgin during the last war, even though two children from the parish died in German captivity. A marble tree (in the vestibule of the church) commemorates their names: Paul Fransolet and Marcel Boudron. Source: https://www.mini-ardenne.be/poi.card.php?language=fr&id=2848
