A vitrified fort originating from the Iron Age, An Dun was probably re-modeled during the early centuries AD by the Vikings and later became the seat of local Mackenzie and Macleod chiefs. Little can now be seen above ground, but excavation has found sections of fire-fused stone walling.
When you walk to the dun from the road, you may well go through a little dip in the ground called 'Leabaidh na Ba Baine' - the bed of the white cow. It's said to have been scooped out by Fingal himself to provide a comfy spot where his white cow could calve.
Mentioned in 'Gairloch in North-west Ross-shire' by John Dixon (1886).
