A ruined hall-house looks across Loch Linnhe from Lismore, with a small bay and older coastal defences close by. Castle Coeffin is a medieval castle ruin, probably built by the MacDougalls of Lorn in the 13th century.
The site is layered with earlier and later associations: a claimed Viking predecessor, a tidal fish trap of unknown date, and a local tale connecting its name with a Danish prince’s haunted sister.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
Castle Coeffin stands on Lismore's north-west coast across Loch Linnhe from Glensanda.
The castle was built on the site of a Viking fortress, according to the source.
It was built in the 13th century, probably by the MacDougalls of Lorn.
Lismore was important in the lordship of Lorn and held St Moluag's Cathedral, the seat of the Bishop of Argyll.
The first written evidence for the castle is from 1469-70, when it was granted to Sir Colin Campbell of Glenorchy by Colin Campbell, 1st Earl of Argyll.
The castle was probably not occupied after the medieval period.
An 1892 gazetteer lists Castle Rachal at the same location as an ancient Scandinavian fortalice and ivy-clad ruin.
