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.

    The castle overlooks the sea loch and Bernera Island.

  • MacDougalls of Lorn

    The family are now considered the likelier medieval builders and holders of the castle.

  • Dunollie

    The MacDougalls may have shifted focus to the mainland and Dunollie in the 15th century.

What to look for

  • Limestone ridge

    The castle occupies the summit of a ridge on the shore.

  • North-east and north-west walls

    These parts of the curtain wall survive most strongly.

  • Courtyard ranges

    Excavation identified at least two building ranges inside the enclosure.

  • Farmstead traces

    The site was reused as a farmstead in the 17th to 19th centuries.
