In Ludwig Roselius’s Coffee Hag albums from the early 20th century, Hillesheim’s arms are shown in somewhat different tinctures.
Berndorf lies between Hillesheim and Kerpen, southwest of the latter in the Vulkaneifel, a part of the Eifel known for its volcanic history, geographical and geological features, and even ongoing activity today, including gases that sometimes well up from the earth.
The municipality is served on weekdays by bus route 522 of the Rhein-Mosel-Verkehrsgesellschaft linking the double village with the nearest town, Gerolstein, as well as with Hillesheim.
In Lissendorf, the historical Dümpelfeld–Lissendorf railway, known as the Middle Ahrtalbahn (“Ahrtal Railway”, Jünkerath–Lissendorf–Hillesheim–Ahrdorf–Dümpelfeld) branched off.
Rockeskyll’s location between Hillesheim and Gerolstein ensured its importance through the ages as a market centre.
