1911 Encyclopædia Britannica/Ahr

AHR, a river of Germany. It is a left-bank tributary of the Rhine, into which it falls at Sinzig, rising in the Eifel mountains, and having a total length of 55 m. It flows at first through rather monotonous country, but the latter portion of its course, from the village of Altenahr, over which tower the ruins of the castle of Ahr, or Are (10th century), is full of romantic beauty. It is well stocked with trout, and the steep declivities of the lower valley furnish red wines of excellent quality.
