Lochindorb Castle is a former stronghold of the Clan Comyn and is built on what now is said to be an artificially created island. The castle is first recorded during the Wars of Independence when Sir John ('the Black') Comyn died there in 1300. By 1455 the castle was in the hands of Archibald Douglas, Earl of Moray, The next year, after Douglas's defeat and death at Arkinholm, Lochindorb was again forfeited to the Crown and this time ordered to be slighted, the work of dismantling its defences being entrusted to the Thane of Cawdor. Since then, it has been left as a ruin.
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.
