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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
