The hilltop where Auchindoun stands bears evidence of prehistoric or Pictish earthworks, suggesting the site was significant long before the castle rose. The visible remains date from the mid-15th century, when the L-plan tower house was constructed -- sometimes attributed to Robert Cochrane, a favourite of James III. The castle had a large central tower, a high curtain wall, and supporting buildings including a stable, brewery, and bakery. A second round tower guarded the northwest corner. Cellars and possibly dungeons were carved directly into the bedrock beneath the main tower. The castle passed to Clan Ogilvy in 1489 and from them to Clan Gordon in 1535, entering the orbit of the powerful Earls of Huntly.

Auchindoun's history is tangled in the feuds of northeast Scotland. An arbitration in 1564 granted Elizabeth Gordon a liferent interest in the castle over her stepson James Ogilvie of Cardell. The most consequential damage came in 1592, when Clan Mackintosh attacked and burned the castle in retaliation for a murder that echoes through Scottish song: the killing of James Stewart, 2nd Earl of Moray, the 'Bonny Earl o' Moray,' by the forces of the Earl of Huntly. The Mackintoshes were allies of the dead earl, and Auchindoun was a Gordon stronghold. The burning was vengeance, pure and methodical.

After the Battle of Glenlivet in October 1594, the wounded followers of the Earl of Huntly retreated to Auchindoun for safety. James VI responded by ordering that Auchindoun, Slains Castle, Huntly Castle, and the Gordon castles of Abergeldy and Newton be slighted or demolished. Following the Restoration of Charles II, the castle was returned to the Marquis of Huntly. In 1689, during the first Jacobite rising, John Graham, Viscount Dundee, used Auchindoun as a temporary headquarters for his Jacobite army on 6 and 7 June. But by 1725 the castle was derelict. Its stones were carried off for use in local farm buildings and in nearby Balvenie Castle -- the same pattern of architectural cannibalism that consumed castles across Scotland when the need for fortification passed and the need for building material remained.

The ballad endures. 'As I came in by Fiddichside, on a May morning / Auchindoun was in a blaze, an hour before the dawning.' The song, collected by Francis James Child as Ballad 183, preserves the Mackintosh attack in the dialect of the northeast, with the image of the castle burning against a pre-dawn sky and the crowing of a cock that has 'burned its crop and lost its wings an hour before the dawning.' The ruins were consolidated and reopened to public viewing in November 2007 after years of being too dangerous to enter. Standing among the fragmentary walls, looking down the glen of the Fiddich toward Dufftown -- the 'Malt Whisky Capital of the World' -- the castle is quiet enough that you might hear the river below. But the song, once you know it, is hard to shake. Someone burned this place on purpose, and someone else turned the burning into music, and the music has outlasted the walls.
