Onich Fort is a Iron Age fort situated in Ballachulish, Inverness-shire, in the Scottish Highlands. The monument occupies ground formed above Appin Group bedrock, a sequence of marble and meta-limestone laid down during the Neoproterozoic era, which contributes to the distinctive geology of this West Highland landscape. The site is protected by Historic Environment Scotland under reference SM2894.
Iron Age forts of this type typically date between the 1st millennium BC and the early centuries AD, serving as defended settlements and centres of territorial control. Their locations were carefully chosen to command surrounding terrain and communicate with neighbouring communities. Onich's position in Ballachulish would have offered strategic advantage over local communication routes and resources in the Lochaber region.
The fort represents an important phase in the settlement history of the Scottish Highlands, when communities fortified their principal settlements with substantial earthwork and stone defences. The preservation of the monument as a scheduled site recognises its significance for understanding Iron Age society and settlement patterns in this part of Highland Scotland.
