The Romans are still very much present in the Saarland nowadays. In the Roman Villa Nennig you can be part of something very special and see a multimedia show about the original Roman villa complex and the Roman mosaic in Nennig.
The Roman mosaic in Nennig is one of the most beautiful and largest examples of Roman mosaic art of the 2nd and 3rd century. North of the Alps, this mosaic is one of the very few that remained at their original site. A local farmer discovered it in 1852 by accident. The mosaic originally formed the centre of a Roman grand villa. Seven picture fields display scenes from an amphitheatre, a colourful, yet gruel scenario.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
