It is known that slabs of marble and diabas were used in the magnificent buildings of the Roman Trier, and also, in large amounts, slabs sawn out of shell limestone. The marble
was imported in large blocks from the South and trimmed for the local construction requirements as close as possible to the town. Diabas, called greenstone by the people in colloquial language, was found in the
Grüneberg, a hill limiting the lower Ruwer valley to the West. This is probably also the reason why the stone bears this name. Up to now, the only remnants of buildings found in the Ruwer valley with a hint to a
Roman mill have been found near the Karlsmühle. In the middle of the last century, archeologists from Trier found strikingly large blocks of shell limestone in the drainage channel of the Karlsmühle – a stone
material which is absolutely non-local in the Ruwer valley. Besides, even today there are still two Roman foundation walls left running towards this mill ditch, now about 20 meters away from the present mill. In the
course of channel construction work through the meadows of the river Ruwer in 1967, a large amount of Roman roof and wall tiles was found, and a part of a Roman stone floor was excavated. The most interesting find
here was made in 1843, when the remnants of a Roman tomb were discovered at the junction of the drainage channel with the river Ruwer. There, a relief can be seen, showing a bust portrait of a man and woman reaching
out to each other, holding hands. To the top, this relief had been limited by a cover stone, with a stone carving showing a mill stone with an axle. Today, this is kept in the State Museum in Trier. This place next
to the Ruwer where the Karlsmühle is situated today has apparently been a mill site without interruption since the times of the Romans. So the Karlmühle’s milling tradition dates back around 1600 years.
