A single stronghold changed hands between three of the West Highlands' great dynasties in turn — MacDougall, MacDonald and Maclean — each forfeiture redrawing who controlled Mull.
Galleys once used the surviving stone landing east of Aros Castle at Salen. Above the Sound of Mull, the broken hall-house (a fortified great hall) and its bailey, the defended yard attached to the castle mound, watched a sea passage rather than a road.
Also recorded as Dounarwyse Castle in later medieval documents, it was raised in the 13th century, most likely by one of the MacDougall lords of Lorn, and changed hands more than once as power in the Hebrides shifted beneath it. When the MacDougalls backed Edward I of England against Robert de Bruys and lost, their lands were forfeited, and King Robert handed the castle to Angus Og of Islay, Lord of the Isles and head of Clan Donald. It served as a working base of that Lordship for over a century, before Clan Maclean in turn took it when the Lordship itself fell from royal favour.
By the 17th century its military importance was fading, though it still had one dramatic episode left: in 1608 Lord Ochiltree used it as the setting to entertain, then arrest, the chiefs of the western clans. Within a century a survey dismissed it as a ruin of no strength at all, and no record of anyone living there survives from the 1700s onward.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
In the 13th century one of the MacDougall lords of Lorn raised a stronghold above the Sound of Mull, choosing a site where a small galley landing could serve the castle directly from the sea below. The result was a hall-house set within a walled bailey (an enclosed defensive yard) built to hold a garrison rather than a household, guarding the narrow water between Mull and the mainland shore.
That command did not last. When the MacDougalls sided with Edward I of England against Robert de Bruys in the Wars of Independence, they backed the losing cause, and their lands, including the castle, were declared forfeit. King Robert then granted it to Angus Og of Islay, Lord of the Isles and head of Clan Donald, folding the stronghold into the growing territory of the Lordship of the Isles.
Documentary evidence from the late 14th century names the castle Dounarwyse and records it in the hands of the Lords of the Isles. Through the late 14th and into the 15th century it served as an occasional base for the Lordship, one of the strongholds the MacDonald lords used as they moved between their island and mainland territories rather than governing from any single fixed seat.
The Lordship of the Isles eventually moved against the crown in its own turn, and when it too had its lands declared forfeit, Clan Maclean gained the castle at Clan Donald's expense. The change of ownership mirrored a wider realignment of power in the Hebrides, as the Macleans emerged as a dominant clan on Mull in place of the MacDonalds who had held the site for so long.
In 1608 Lord Ochiltree used Aros as the setting to entertain the Hebridean island chiefs before turning host into captor and taking them prisoner there, an episode carried out as part of a drive to bring the western chiefs under closer royal control. It marked one of the castle's last recorded moments of real political weight. By 1688 the castle was described as ruinous, old, useless and never of any strength, yet Argyll's troops still seem to have garrisoned it in 1690 during the unrest of that period. No evidence of any occupation survives from the 18th century onward, and the castle was left to decay into the ruin that stands today.
