Traben-Trarbach is one of the most charming wine towns along the Mosel River, in the Rhineland-Palatinate region of Germany. In addition to its vineyards, it is famous for its castle ruins and fine Jugendstil architecture.Traben and Trarbach used to be separate villages on opposite sides of the Mosel River connected by a bridge. In 1904, the cities merged to become Traben-Trarbach. In 1969, the city annexed Wolf, a village 4½ km north of downtown Traben-Trarbach, also located on a bend in the Mosel River.
