Ballinafad Castle is an Elizabethan blockhouse built during the Nine Years' War by Captain John St. Barbe on land granted to him by King James VI and I. The castle was garrisoned by ten men and commanded by John St. Barbe. It was partially destroyed by Red Hugh O’Donnel in 1595. The castle was again sacked in 1642 and fell out of use by 1680.
Today it is in ruins and is accessible year round. There are no tours, guides, or fees. Visitors can park in a small carpark at the foot of the hill where they will find an interpretive sign. Visitors cannot enter the castle, but the interior is visible through breaches in the walls that are closed off by iron fences.
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.
