Dating from the mid 16th Century the ruined remains of Carnassarie Castle lie to the north of Kilmartin in Argyll and Bute. Built by John Carswell, it passed to the Campbells of Auchinbreck in 1572 and was finally destroyed in 1685 when its owner, Sir Douglas Campbell, joined forces with the Earl of Argyll in the Monmouth Rising and the Royalist forces of MacLaine of Torloisk blew up the castle. It is now under the guardianship of Historic Scotland.
