Pastor Franz Josef Fuchs had the Lourdes Grotto built into the northern slope of Hohenberg Mountain. It was consecrated on June 20, 1886. Glass particles from the Rosenberg glass factory can still be seen in the Lourdes Grotto today. Slag stones from the disused glass factory were used as building material, into which various colored glass was melted. The grotto is freely accessible and can be reached via a path northwest of the pilgrimage church of St. James. It is located in a small wooded area directly next to a small pond. Cycling is prohibited, but you can easily push your bike down from Hohenberg Mountain; there are a few steps at the bottom. You can continue by bike from the grotto.
