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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
