The Roman-Germanic Museum (Römisch-Germanisches Museum) has a large collection of Roman artifacts from the Roman settlement of Colonia Claudia Ara Agrippinensium, on which modern Cologne is built. The museum protects the original site of a Roman town villa, from which a large Dionysus mosaic remains in its original place in the basement, and the related Roman Road just outside. In this respect the museum is an archaeological site.
The Römisch-Germanisches Museum is near the Cologne Cathedral on the site of a 3rd-century villa. The villa was discovered in 1941 during the construction of an air-raid shelter. On the floor of the main room of the villa is the renowned Dionysus mosaic. Since the mosaic could not be moved easily, the architects Klaus Renner and Heinz Röcke designed the museum around the mosaic. The inner courtyards of the museum mimic the layout of the ancient villa.
In addition to the Dionysus mosaic, which dates from around A.D. 220/230, there is the reconstructed sepulcher of legionary Poblicius (about A.D. 40). There is also an extensive collection of Roman glassware as well as an array of Roman and medieval jewellery. Many artifacts of everyday life in Roman Cologne are displayed, ncluding portraits (e.g., of Roman emperor Augustus and his wife Livia Drusilla), inscriptions, pottery, and architectural fragments.
The museum has the world's largest collection of locally produced glass from the Roman period.
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.
