It rises in the lower Devonian rocks of the Eifel range, and, after a swift course of 5 m., joins the latter river at Mosel kern, nearly 20 M. S.W. of Coblenz. Just above its confluence stands the romantic castle of Eltz, crowning a rocky summit goo ft. high, and famous as being one of the best preserved mediaeval strongholds of Germany. It is the ancestral seat of the counts of Eltz and contains numerous antiquities.
