サムニウム戦争
In ancient times, Circello was a Samnite city. This zone, according to Titus Livius, was called "Taurasia". The territories of Upper Samnium were conquered by the Romans following the Samnite Wars, and the area around Circello became "Ager publicus", that is public land belonging to the Roman people. Excavations in the area, in particular in the Macchia district, demonstrate the Roman presence in Circello.
