The Breno castle rises on a hill overlooking the town: the building was erected in the 12th century, then turned into a military stronghold at the time of the Venetian Republic (1400-1500) and finally, after being abandoned in 1598, it was reused as a stone quarry.
The castle however rises on a much more ancient site: probably the place where in the 10th-9th century BCE a prehistoric community settled.
You can reach the castle with a short walk (about 15 minutes) from the centre of Breno: the perimeter is closed by a battlemented boundary wall and by two towers. Inside you can admire the remains of the St. Michele church, of Longobard origin, then enlarged in the Romanesque period. The other buildings, the only remains of which are mostly the outside walls and the cellars with barrel vaults, were added during the Venetian reign.
References: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.
