The municipality lies 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.

Near the village and in the outlying centre of Niederkyll, many finds from Roman times have been unearthed during excavation work.

After these fires, the old town wall served as a quarry of sorts for building material to rebuild the village.

The wall completely disappeared as a result, and its alignment can now only be made out in the rows of houses on Burgbergstraße.

The heaviest destruction sustained by Stadtkyll, however, came in the air raids in December 1944 and just after New Year's, late in the Second World War, after the Battle of the Bulge.

The outlying centre of Schönfeld was bound to pay tributes to Prüm Abbey in the 13th century.

The bend sinister in the old arms has been made wavy, however, and a silver bendlet has been added to its lower edge, to symbolize that the village's and the castle's surroundings are shaped by their location on the river Kyll.

Scientific interpretation has raised the possibility that it might be part of a grave, given that it is near the old Roman camp of Icorigium (now Jünkerath).

Stadtkyll is a state-recognized climatic spa (Luftkurort) and records in its many lodging facilities roughly 70,000 holiday guests with some 300,000 overnight stays each year.

One of the main attractions is a heated open-air community swimming pool with a giant chute and a rope swing.
