Asgog Castle, situated on the northwest shore of the Asgog Loch, on the Cowal Peninsula, Argyll and Bute, west of Scotland, was once the home of a cadet branch of Clan Lamont. It was first recorded in 1581, but may be mid-15th-century in date. In 1646, the castle was besieged and eventually destroyed by Clan Campbell,[1] during the conflict now known as the Dunoon massacre. Only three walls of the keep are now standing; of the courtyard, there are no identifiable remains.[2] [3]
