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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
