Sorry, I have not. However, I know the area and I looked at this http://www.saarburg.de/frameengl.html.

Trier, Germany's oldest city:
ANTE ROMAM TREVERIS STETIT ANNIS MILLE TRECENTIS.
"Trier was there one thousand and three hundred years before Rome", that's what an inscription on the Red House in the Main Market says. It's an invention of the Middle Ages, but it has an historical background. In the valley of Trier there were indeed human settlements already in the 3rd millennium before Christ, and Trier was the first place in Germany which could really be called a city...
And Karl Marx was born in Trier ...
