Senerchia (Sinerchia in the local dialect) is an Italian municipality with 1370 registered voters, but only 1036 inhabitants, in the Province of Avellino, located in the upper valley of the Sele River in Campania.

The village is located 600 metres (2,000 ft) above sea level in the High Sele Valley, in a hilly area on the eastern side of the Picentini Mountains, at the foot of the steep slopes of Mount Boschetiello.

In addition to the Sele, which skirts the municipal area, other waterways include the Vallone Forma, Piceglia, Fiumicello Rovivo, Pozzo San Nicola and Acquabianca.

The final battle that saw the defeat and death of Spartacus in 71 BC took place in the present-day territory of Senerchia, on a site on the right bank of the river Sele in an area that includes the border with Oliveto Citra up to Calabritto, near the village of Quaglietta.

They took part in many feuds between Campania, Basilicata, and Apulia, and lived mainly between Senerchia and Naples until the fifteenth century.

The Sinerchia, transplanted later to the Basilicata region, were honored with the title of Count in the fifteenth century, and following the 1481 Conspiracy of the Barons assumed the surname of Scardaccione.

Orlando Sinerchia Scardaccione, Count of Sant’Andrea, when he moved to Potenza, together with his cousin Amelio, was deprived of his estates as a consequence of the Conspiracy of the Barons.

It may already have been the defensive garrison of Irpini, and the Romans probably had to work hard to subdue it; hence the Latin name Sena Herclea (which means Bosom of Hercules).
