The area around Dunachton shows evidence of human occupation in prehistory, with flintwork and whetstones being found in the vicinity. The name Dunachton derives from Dun Neachdain the fort of Nechtan. Nechtan's identity is unknown, but it is likely he was one of several of the early Pictish Kings that went by that name. Dunachton had some importance in the Early Medieval period. It is the site of an early class I Pictish stone which was discovered in 1870, having been recycled as a lintel stone in a farmstead building. Dunachton is first documented as 'Dwnachtan' in 1381, in reference to the 'capelle de Nachtan', the Chapel of Nechtan, which was dedicated to St Drostan. Recent research has pointed to the possibility that Dunachton may have been the correct site of the Battle of Dun Nechtain in 685, when Bridei mac Bille, king of the Pictish kingdom of Fortriu defeated Ecgfrith of Northumbria, securing Pictish independence from Northumbria. The battle site was previously thought to be somewhere in the vicinity of Dunnichen in Angus, but reappraisal of the scant documentary evidence along with the reappraisal of Fortriu as being north of the Grampian Mountains has led to the suggestion that Dunachton is the true location. Dunachton Lodge was built on the remains of Dunachton Castle. The landowners were originally the MacNivens, who as a sept of the MacNaughtons, claim descent from Nechtan. The barony subsequently came into possession of the Clan Mackintosh in the early 16th century through the marriage of Isabel MacNiven, the heiress of the Barony of Dunachton to William Mackintosh, cousin of the chief of the clan Mackintosh, and later chief of Clan Mackintosh and the wider Chattan Confederation. A centuries-old feud between the Mackintoshes and Clan MacDonald of Keppoch came to a head in 1688 at the Battle of Maol Ruadh. Dunachton Castle was destroyed the following year by Coll MacDonald under the auspices of the Jacobite cause, provoking a public rebuke from Dundee. It was never rebuilt. Dunachton was bought in the 1950s by Andrew Forbes-Leith, who later inherited the baronetcy of Fyvie. In the 1970s he turned of Dunachton into the Highland Wildlife Park.
