In the 4th century BC there was a sanctuary dedicated to the goddess Feronia located in the centre of the natural depression now called Pantano, which was probably frequented by the populations who lived in huts on the nearby hilltops.

In the first half of the 2nd c. AD important and impressive buildings were erected with the support of the powerful senatorial family of the area, the Brutti Praesentes, notably the amphitheatre, baths and forum built on a terrace.

Excavations from 2000 uncovered the porch of the temple of Feronia originally made from wood, that was replaced later by walls of travertine and bricks.

In 2022 at nearby Castellano, an imposing rectangular cistern 100 m long, almost 5 m wide and high, fed by 10 wells and with a capacity of about 80,000 litres was discovered.

It is a castellum aquae, with 3 chambers from which lead pipes led the water towards the Forum and the town, with a reverse siphon system.
