Kilchurn Castle is a ruined 15th and 17th century structure on a rocky peninsula at the northeastern end of Loch Awe, in Argyll and Bute, Scotland. Wikipedia Access to the Castle is sometimes restricted by higher-than-usual levels of water in the Loch, at which times the site effectively becomes a temporary island.

It was the ancestral home of the Campbells of Glen Orchy, who later became the Earls of Breadalbane also known as the Breadalbane family branch, of the Clan Campbell. The earliest construction on the castle was the towerhouse and Laich Hall (looks onto Loch Awe).
