Erchless Castle is an iron age dun situated 650 metres west-north-west of Erchless in Inverness-shire, Scotland. Duns were substantial circular or oval stone-built fortifications typical of iron age settlement in northern Britain, serving as defensive homesteads for local élites and their households. This example stands on bedrock of psammite—a metamorphic sandstone—belonging to the Loch Eil Group, which was formed during the Neoproterozoic era and forms part of the Dalradian metamorphic rocks that underlie much of the Scottish Highlands.
The dun's location on this ancient metamorphic geology is characteristic of iron age settlement in the region, where communities selected defensible positions offering natural outcrops suitable for stone construction. The psammite bedrock would have provided ready-worked stone for the substantial walls that define such fortifications, allowing builders to exploit natural rock faces and boulders in their construction.
Erchless Castle is protected as a scheduled monument under Historic Environment Scotland's reference SM5004, recognising its significance as a surviving example of iron age defensive architecture in the Highlands. The site contributes to understanding settlement patterns and building traditions in the region during the pre-Roman iron age period.
