Nonnenbach (Ahr)

The Nonnenbach is a seven-kilometre-long tributary of the Ahr in the area of Blankenheim in the district of Euskirchen in the German state of North Rhine-Westphalia.

Course
The source of the Nonnenbach lies in woods about 2 kilometres east of Schmidtheim, on the far side of the B 51 and not far from gravel pits already partly filled with groundwater. It flows past the eponymous village and empties into the Ahr a good 2 kilometres south of Blankenheim. Apart from the Seidenbach and the Günzelbach it is also fed during its short course by the streams of numerous gullies, known locally as Seifen.
