As it stood in 1400
The shape it held in its prime.
Set on a rocky north-west promontory of Lismore, the castle in its prime is a compact stone complex: a single large oblong hall-house (about 20.3 by 10.4 m) with very thick masonry walls and an attached, irregularly shaped bailey defended by lower stone enclosures. The entrance lies in the north-east wall with an external stair linking down to the bailey; a second doorway opens to the sea on the south-west side. The site faces Loch Linnhe with open sea views to Glensanda.
Its story
The story of Coeffin.
Castle Coeffin stands on a promontory on the north-west coast of Lismore in Loch Linnhe, facing Glensanda across the water — the island that was also home to Moluag's Cathedral, seat of the Bishop of Argyll. Built in the 13th century, the castle comprises an oblong hall-house with a later, irregular bailey.
The castle's first written record comes in 1469–70, when it was granted to Sir Colin Campbell of Glenorchy by Colin Campbell, 1st Earl of Argyll. It has not been regularly occupied since the post-medieval period, and survives as a ruin on its rocky headland.
