The Vigna Cassia catacombs located next to thel Parco Archeologico Neapolis, owe their name to the family that owned the vineyard (at the time of discovery), which was located above the catacombs themselves.
They were found in 1852 during excavations by the Commission of Antiquities and Fine Arts, which at the discovery of steps carved into the rock that led to about 15 meters below street level, decided to deepen the research. After the excavations they discovered that the steps continued to a depth of 25 metres and that they led to the beginning of a series of tunnels.
The Catacombs of Vigna Cassia are considered the largest in Sicily, the beginning of their construction dates back to the third century AD, were active from the second half of the fourth century AD and presented themselves as a real cemetery consisting of a ipogeo of communities, but also five private hypogeums (intended for individual burials).
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.
