Dunscaith Castle is named after and was the home of the warrior maiden Scáthach. The castle itself sits on an off-shore rock. There is a gap between the rock and the mainland which was once spanned by a walled bridge. This stone walled bridge then led onto a drawbridge, the pivot holes for which are still visible on the far side. Once on the other side of the drawbridge a door opened to a flight of stairs which was also sided by two walls. The flight of stairs led up to the castle.
Parts of the castle curtain wall still survive on the cliff edge but most of the inner buildings have gone. The curtain wall was about 5 ft thick. In the courtyard is a well and the remains of a stairway which once led up a tower.
Originally the castle belonged to the Clan MacDonald of Sleat, a branch of the Clan Donald or MacDonald. At some time in the 14th century it was taken from them by the Clan MacLeod and held briefly by the MacAskills, allies of the MacLeods but it was recaptured by the MacDonalds sometime in the 15th century.
In the 15th century the castle was again captured by King James I of Scotland when the Chief of the Clan Donald, Lord of the Isles was broken by King James I. The MacDonalds were allowed to keep possession of the castle. The MacDonalds abandoned the castle in the early 17th century.
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.
