Grumentum was an ancient Roman city in the centre of Lucania, in what is now the comune of Grumento Nova. The first Lucanian settlements in the area date from the 6th century BC. The site was founded by the Romans in the 3rd century BC during the Samnite Wars as a fortified vanguard. In 215 BC the Carthaginian general Hanno was defeated under its walls at the Battle of Grumentum, but in 207 BC Hannibal made it his headquarters.
In the Social War it was a strong fortress, and seems to have been held by both sides at different times but was sacked by Italic tribes. It became a colony, perhaps in the time of Sulla, at the latest under Augustus, and became important.
St. Laverius was martyred here in 312 AD. In 370 AD Grumentum became a bishopric but soon afterwards it began to be abandoned. Due to the Saracen inroads (9th-10th centuries), in 954 a new town (Saponara or Saponaria, the modern Grumento Nova) was founded.
Its ruins include those of a large amphitheatre (1st century BC), the only one in Lucania. There are also remains of a theatre. Inscriptions record the repair of its town walls and the construction of thermae (of which remains were found) in 57–51 BC, the construction in 43 BC, of a portico, remains of which may be seen along an ancient road, at right angles to the main road, which traversed Grumentum from south to north. A domus with 4th century mosaics is also present, as well as two small temples of imperial times. Outside the walls monumental tombs, a Palaeo-Christian basilica and an aqueduct have been found.
The aqueduct had its source about 5 km further south and entered the town on the southern side of the plateau. It was transported on arches and emptied into a Castellum Aquae of which some ruins remain.
Many of the finds can be seen in the Archaeological Museum of Grumento Nova.
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.
