Hellenburg Castle was probably built around 1300. After some renovations and additions, which took place in the 14th and 15th century, the castle got its final shape in 1450. The castle was lost as a result of a flooding caused by a storm disaster in 1477. In the 17th century nothing more remained than a ruin. These ruins were demolished in the 18th century, its stones used as building materials by the villagers of Baarland and the location of the castle was forgotten. The ruins were found accidentally in 1957. Today the foundations have been reserved.

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.
