The Castello di Lombardia iis one of the largest and most ancient edifices in Italy, with an area of some 26,000 m2.
The castle's origins are related to a fortress erected in the 1st millennium BC by the Sicani on the foundation of the ancient Henna, on a hill 970 m above sea level. It remained a key possession in the subsequent history of the island, and the Romans were able to conquer it only by passing through its sewer network.
Under the castle was the ancient Sican temple of Ceres, site of the widespread cult of that goddess in the whole of Italy, which was described by Cicero.
After the fall of the Western Roman Empire, it was used by the Byzantines and resisted Arab assaults for many years. After their victory, the latter rebuilt the fortress around the 10th century; the castle was also used by their successors in Sicily, the Normans. Two centuries later, architect Richard of Lentini was commissioned by Frederick II, Emperor and King of Sicily, to restore it as a summer residence. He added 20 towers and called in a garrison coming from the Langobardia minor (Calabria), whence the castle's name.
With the advent of the artillery, the castle lost its primary strategic role and was turned into a prison. In the 20th and early 21st century, the castle was the site of the Teatro più vicino alle Stelle, used for opera and pop music concerts. The castle is now open to the public.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. 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.
