The Castle of Monteforte was probably an ancient Roman castrum, on which a real castle was probably built by the Lombards in the 7th-8th century. But the history of Monteforte is very ancient: traces of its existence can be found already during the Second Punic War (fought between Rome and Carthage from 218 BC to 202 BC), when Annibale Barca passed through it on his way back from Capua towards Cannae, where he prepared the historic trap against the Romans. The first certain information we have about the village is contained in a document from 1102 preserved in the Montevergine Archives. In the Angevin period, it passed to the Princes of Montfort and Count Guido de Monfort lived there, who killed Prince Henry of England in 1271 in the cathedral of Viterbo. Having committed the crime, he was deprived of his possessions which passed to the Orsini family, whose lineage they remained in until 1806. The Castle was renovated and transformed into a summer residence by Charles of Anjou who lived there several times from 1271 to 1280. It was abandoned to itself from the 16th century; legend has it that who knows what treasures were buried in it, unfortunately this gave greedy hands the opportunity to complete its destruction.
