Skipness Castle was built in the early 13th century by the Clan MacSween with later fortifications and other additions made to the castle through the 13th, 14th and 16th centuries. The castle was garrisoned with royal troops in 1494 during King James IV of Scotland's suppression of the Isles. Archibald Campbell, 2nd Earl of Argyll granted Skipness to his younger son Archibald Campbell in 1511.
During the Wars of the Three Kingdoms in 1646, the castle was besieged by forces under the command of Alasdair Mac Colla. During the siege, Alasdair's brother, Gilleasbuig Mac Colla, was killed in August 1646. The castle was abandoned in the 17th century. The Green Lady of Skipness Castle is said to haunt the location.
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.
