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 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.
