#128 Germany

The Lahn River is a 245.6-km-long, right (or eastern) tributary of the Rhine River in Germany. It has its source in the Rothaargebirge, the highest part of the Sauerland. It meets the Rhine at Lahnstein, near Koblenz. Important cities along the Lahn include Marburg, Gießen, Wetzlar, Limburg an der Lahn, Weilburg and Bad Ems.

The lower Lahn has many dams with locks, allowing regular shipping from its mouth up to Runkel. Riverboats are also used on a small section north of the dam in Gießen. (source)
