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:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
