Blankenheim is located in the Eifel hills, approx. 27 km south-west of Euskirchen. The river Ahr has its source in the centre of Blankenheim, in the cellar of a half timbered house.
In the year 721 Blankenheim is mentioned for the first time as "Blancio" in a document. Today the municipality is called in Eifel dialect as "Blangem" and has got a long carnival tradition.<br style="clear: left;"/>
