Cairnburgh Castle

Cairnburgh Castle is a small island fortress occupying the two tidal islets Cairn na Burgh Mòr and Cairn na Burgh Beag at the mouth of Loch Tuath, off Mull. The fortification consists of a compact cluster of stone buildings, a courtyard and guard-houses split between the larger and smaller islet; its position on sheer sea cliffs made it a naturally strong defensive site.

What Cairnburgh Castle looked like in its prime.

Two flat-topped rocky islets rise sheer from the sea, their rounded silhouettes topped by a compact cluster of low grey masonry buildings. On the larger islet a long barrack block, a small chapel and an open courtyard are packed close to the cliff edge, with a guard-house anchoring the defence; the smaller islet holds a single guard-house and a stone-lined well. The whole complex reads as a low, horizontal, stone-built fortification clinging to exposed sea cliffs.

Its story

The story of Cairnburgh Castle.

Cairnburgh may have begun as a Viking fortress called Kiarnaborg, and its defences straddle two islands at the mouth of Loch Tuath: Cairn na Burgh Mòr, with a barrack block, chapel, courtyard and guard-house, and Cairn na Burgh Beag, with a second guard-house and a well. The 13th-century Hákonar saga Hákonarsonar records it as the property of an island king of the family of Somerled, demanded of him by Alexander III of Scotland.

From at least 1249 to 1269 the castle was held by Clan MacDougall, descendants of Somerled through his son Dubgall. When the MacDougalls backed John de Balliol against Robert de Brus in the Wars of Scottish Independence, the Crown seized the castle; after temporary occupation by Clan MacDonald it became the property of Clan MacLean. A 1409 charter from Donald of Islay, Lord of the Isles described his nephew Hector Maclean as Lord of Duart Castle and constable of the castle of Cairnburg.

Under the MacLeans the castle saw several conflicts but was extremely well defended by its surrounding cliffs; James IV besieged it in 1504 when the MacLeans rebelled in favour of Domhnall Dubh, chief of Clan Donald. It remains, in the words of The Changing Scottish Landscape, "one of the most isolated fortifications in Britain...[and] also one of the strangest."
