Aros Castle, also known as Dounarwyse Castle, is a striking medieval ruin perched above the Sound of Mull near the village of Salen. Once a powerful hall-house stronghold guarding the busy sea route between Mull and the mainland, it now stands as one of the top sights in Mull for history lovers and anyone seeking a quiet, dramatic viewpoint. Visitors can walk around the ruins at their own risk, enjoying views across the water and imagining the turbulent centuries this site has witnessed.

The castle's strategic position is clear the moment you arrive. A steep drop protects the seaward side, while a deep man-made ditch once defended the landward approach. Though roofless and weathered, Aros Castle remains an evocative reminder of medieval clan rivalries and shifting power struggles.

History and Significance of Aros Castle

Aros Castle was likely built in the 13th century by the MacDougall lords of Lorn, who maintained several important strongholds across the western seaboard. Later documents record it as Dounarwyse Castle in the late 14th century, by which time it belonged to the powerful Lords of the Isles.

The castle changed hands repeatedly over the centuries as political fortunes shifted. After the MacDougalls backed the losing side in the conflict between John Balliol and Robert the Bruce, their lands were forfeited and Aros passed to Clan Donald. Centuries later, when Clan Donald lost favour for attempting to challenge Scottish authority, Aros was transferred once again—this time to Clan MacLean.

In 1608, Lord Ochiltree gathered island chiefs at Aros only to imprison them, a dramatic episode underscoring its once-important role. By 1688, the castle was described as ruinous and weak, though it was still garrisoned by Argyll’s troops in 1690. No evidence suggests occupation after the early 18th century.

Things to See and Do in Aros Castle

Visitors can explore the hall-house remains, which originally featured two main storeys and a partial attic. The defensive ditch, traces of the bailey, and outlines of later buildings can still be seen. A small stone landing place east of the bailey hints at its maritime importance, giving arriving boats direct access to the stronghold.

The site offers excellent views over the Sound of Mull, making it a peaceful place for photography and reflection. Standing within the ruined walls, it is easy to imagine the era when Aros Castle controlled one of the island's key sea routes.
