Lying along a gorge dominated by two fortresses, the Nera river of medieval origin divides the town into two parts, Mattarella and Precetto. The origins of the town date back to the eighth century and its history is linked to that of the Abbey of S. Pietro in Valle; at first a free municipality, then under the lordship of the Cybo and the Ancaiani, it fought for a long time against Montefranco and Spoleto. The vicissitudes of Ferentillo always followed those of the Abbey and the abbey fiefdom tried to make itself independent from both the Duchy of Spoleto and the Lateran Chapter; the territory became a small state in 1484 thanks to Pope Innocent VIII Cybo who appointed his nephew Franceschetto Cybo as the first Lord. He married Maddalena de Medici and in 1515 his son, Lorenzo Cybo, married Ricciarda Malaspina, thus uniting Ferentillo to the Principality of Massa Carrara and Piombino.
