Sieg

The source is located in the Rothaargebirge[?] mountains. From here the river runs southwestwards to the city of Siegen[?] and the hills of Siegerland[?], both named after the river. Further west the Sieg valley forms the northern boundary of the Westerwald region. The river finally runs through the hills of the Bergisches Land and enters the industrial region surrounding the city of Bonn.

After passing the cities of Hennef[?] and Siegburg[?] it joins the Rhine just a few kilometres north of the centre of Bonn.
