Standing at the head of Loch Awe on what is today a low, rocky mound, but which, in medieval times, was an island, Kilchurn Castle was built, probably, around 1440 by Margaret, wife of Sir Colin Campbell, first Laird of Glenurquhay. This original 5-storey keep, later extensively improved and extended, was to be well-tested in battle - enduring a siege by Royalists during the Civil War. Later, although by now already a partial ruin, it was used to garrison Hanoverian troops in the tumultuous days of the Jacobite Risings.
