From the web: "The construction of the castle began in the 9th century at the behest of Rainaldo, Count of the Marsi. This fortress, together with other towers connected by walls, was built to defend itself from the incursions of the Saracens and the Hungarians.
In 1096, the castle passed into the hands of Aldegrina or Aldegrima, wife of a descendant of the founder and countess of Carsoli. It was she who donated the castle to the Abbey of Montecassino in the same year.
In 1242, the castle was attacked by Frederick II after the destruction of Carsoli, when the fugitives took refuge in Oricola. In 1381, Oricola became a fiefdom of the Orsini, and in the fifteenth century it underwent a renovation that gave it its current appearance.
The castle, located in a dominant position on the Cavaliere plain, has a triangular plan with three cylindrical towers at the corners. The two towers of the eastern facade have been completely renovated, while the western one still retains the characteristics of the original construction. The north-west part of the building houses municipal offices, while the rest of the castle is privately owned".
