After the Roman one, Pietraroja has undergone the various dominations of Samnium (Lombard, Norman, Hohenstaufen, Angevin, Catalan-Aragonese, Spanish, etc.). After Lombard rule under the gastalds of Telese, Pietraroja was part, from the 12th to the 14th century, of the fief of the Sanframondos, a family of Norman origin. Their possessions included, among the others, the territories of Cerreto Sannita, Cusano Mutri, Pietraroja, Guardia Sanframondi, Limatola, San Lorenzo Maggiore, Massa, Faicchio, Ponte as well as Dugenta in Terra di Lavoro and Bojano and San Giuliano del Sannio in Molise.
