This Lourdes Grotto is also a sign of solidarity between Catholics and Protestants in Dernbach: "Every Whit Monday, a Catholic service takes place at the Lourdes Grotto in Dernbach. The Protestant parish deliberately does not hold its own service on this day, but invites people to the service at the Lourdes Grotto."
