Lochranza Castle dates from the 13th century when it was owned by the MacSweens. In 1262, King Alexander III granted the castle and its lands to Walter Stewart, the Earl of Menteith. It is believed that Robert the Bruce landed at Lochranza in 1306 on his return from Ireland to claim the Scottish throne. By 1371, the castle was the property of Robert II. It is thought that at this time it was used as a royal hunting lodge.
During the 1490s, James IV used the castle in his campaign against the Lord of the Isles and the Clan MacDonald. In 1614 it was occupied by James VI and in the 1650s it was used by Cromwell. By 1705, Lochranza Castle was the property of the Hamilton family, after it was purchased by the Duchess of Hamilton. The Hamiltons had owned other estates on the Isle of Arran so eventually sold it to the Blackwood-Davidson family who used it as their principal seat. During the 18th century, the castle fell into disuse and was abandoned. The castle is now in the care of Historic Scotland.
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.
