 The arms go back to a seal used in 1747.The single charge in the arms, an eight-spoked wheel, is a reference to the municipality's name, derived, it is believed, from the village's having arisen at a crossroads that would have seen traffic equipped with such wheels, namely "Wagen" (from which the first syllable "Wahn—" supposedly derives).The wheel's tincture, azure (blue), refers to the arms once borne by the Counts of Veldenz.
