Geography edit
Course edit
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.
