In 1582, the MacDougalls built Gylen Castle on an island near their former capital. However, in the civil war of the next century, Archibald Campbell (Sir Colin's heir) was the de facto head of the Covenanter government, while the MacDougalls were Royalists; a Covenanter army (under General Leslie) therefore burnt Gylen Castle down, which they also did to Dunollie. However, Archibald's son was a royalist, so the Campbells ultimately retained their status, despite the eventual fall of the Covenanter regime.
