Tongue House is the historic seat of the Clan Mackay, after they abandoned Castle Varrich (Caisteal Bharraich). The ruins of the castle, built at Tongue in the eleventh century after the clan were expelled from their ancestral Province of Moray to County Sutherland, are a popular tourist attraction. A battle for succession some time around 1427 to 1433 culminated in the Battle of Drumnacoub, in which two factions of the clan fought on Carn Fada, between the Kyle and Ben Loyal.
