Limestone rises above the north-west shore of Lismore, carrying the broken curtain walls of Achanduin Castle over Loch Linnhe. The ruin is a medieval castle, probably built by the MacDougalls around 1290, though it was long associated with the bishops of Argyll.
Excavations in the 1970s complicated the older story. They revealed ranges inside the courtyard, possible pre-castle activity, and a later life as a farmstead after the castle’s main medieval occupation had faded.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
Achanduin Castle dates from the 13th century.
Recent research makes a MacDougall origin around 1290 more likely than construction by the Bishop of Argyll.
A 1304 grant made at Achichendone shows the castle in MacDougall hands.
The MacDougalls forfeited many possessions after 1308, following the Battle of the Pass of Brander and the loss of Dunstaffnage.
The castle saw little occupation from about 1400 until its later use as a farmstead.
Dennis Turner excavated Achanduin over six seasons between 1970 and 1975.
Worked stone of prehistoric type was found, suggesting possible prehistoric activity on the ridge.
