The existence of the castle is attested in 1097, but it was probably of Lombard origin. Initially a dominion of the Girini (or Girindi) family, it was later under the seignories of Veroli and D'Aquino. The town and countryside are dominated with the Viselli, Valeri, Tomassi, Lisi, Sementilli, Maini, DeVellis and Casagrande family lines.
