Saint-Léon hamlet is a part of Walscheid village. You may enjoy Saint-Léon Chapel and Saint-Léon Grotto which is 32m deep, 24m wide and 8m high. When you enter the cave, on the left, you may see a commemorative plaque in memory of Pope Saint Léon IX: it is said he withdrew to this cave. He may have come here to pray and meditate when he was young.
