Mentioned by Pliny the Elder, the Cervaro river which starts from Daunia mountains in Puglia, for part of its way flows in Irpinia, in the borders with the province of Foggia, in the upper part of the valley which bears its name.

In that area suited for sheep farming where the Pescasseroli-Candela and Camporeale-Foggia tratturo (mountain grassy paths) were passing through, in the Irpina part,  the hamlets of Zungoli, Savignano and Ariano Irpino appear.
