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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
