[2] The regimental colours of the WW1 Canadian Expeditionary Force 236th Battalion (New Brunswick Kilties), CEF are laid up in the Great Hall.

[4] John of Islay's son, Donald Macdonald, Lord of the Isles, confirmed the castle by charter to the Macleans in 1390.

In September 1653, a Cromwellian task force of six ships anchored off the castle, but the Macleans had already fled to Tiree.

To the north of the castle is a Historic Marine Protected Area within which lie the remains of a wrecked 17th century warship, believed to be the Swan.

[5] In 1678, the 9th Earl of Argyll, Chief of Clan Campbell and son of the late 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 3rd Earl of Seaforth.

In 2012, the centenary of the 1912 restoration, the Chief of Clan Maclean announced that his family could no longer afford the upkeep of the castle in light of the expense of major repairs.
