The castle of Arena was built by the Norman king Roger I the 11th century, to protect the pass of Berra and to defend the dominions on the Tyrrhenian side of the greenhouses against the risk of potential attacks from the eastern side, where Byzantines and Arabs had important positions.
The administrative and military control of the feud of Arena was entrusted to the Conclubet family, which for over 600 years was confirmed in power by the different dominations that succeeded one another in Calabria ultra, to which the Acquaviva dukes took over in the sixteenth century.
The ruins of the castle, substantially destroyed by the earthquake of 1783, preserve the Norman architectural structure, with large perimeter walls and the main building in the shape of a quadrilateral.
At the corners of the quadrilateral there are four partially preserved towers, belonging to different periods during which the castle underwent various technical – defensive adaptations.
Thus, in the Angevin age, the original quadrangular towers with smooth shoe of the Norman tradition, were replaced on the eastern side by high towers with a circular base and grooved shoe, the latter aimed at increasing the results of the so-called “plumbing defense” technique. increasing the range and lethality of the projectiles launched from the walls. Just the grooved shoe base is a constructive rarity since the typical Angevin tower had a smooth shoe.
On the western side, the Norman towers were modified only in the Aragonese period, when the development of artillery made it necessary to lower and strengthen them.

Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
