Duart Castle dates back to the 13th century and is the seat of Clan MacLean. In 1647, Duart Castle was attacked and laid siege to by the Argyll government troops of Clan Campbell, but they were defeated and driven off by the Royalist troops of Clan MacLean. In September 1653, a Cromwellian task force of six ships anchored off the castle, but the Macleans had already fled to Tiree. A storm blew up on the 13 September and three ships were lost, including HMS Swan.
In 1678, Archibald Campbell, 9th Earl of Argyll, son of the Marquess of Argyll, successfully invaded the Clan MacLean lands on the Isle of Mull and Sir John Maclean, 4th Baronet fled the castle and withdrew to Cairnbulg Castle, and afterward to Kintail under the protection of the Earl of Seaforth. In 1691 Duart Castle was surrendered by Sir John Maclean, 4th Baronet to Archibald Campbell, 1st Duke of Argyll. The Campbell clan demolished the castle, and the stones from the walls were scattered. Donald Maclean, 5th Laird of Torloisk used some of the stones to build a cottage for his family close to the site of the castle. By 1751 the remains of the castle were abandoned.
Descendants of Archibald Campbell, 1st Duke of Argyll sold the castle in 1801, to MacQuarrie, who then sold it to Carter-Campbell of Possil who kept it as a ruin within the grounds of his own estate to the north, Torosay Castle. He later sold his Torosay Estate which now included the ruins of Castle Duart to A. C. Guthrie in 1865. On 11 September 1911, the ruin was separated from the rest of the Torosay Estate and was bought by Sir Fitzroy Donald Maclean, the 26th Chief of the Clan MacLean and restored.
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.
