Dun Dornaigil

Dun Dornaigil (also Dun Dornadilla) is an Iron Age broch in Strathmore, Sutherland, probably built in the 1st century BC. Its most striking feature is a massive triangular lintel stone above the entrance, considered the best surviving example of its kind in Scotland. The surrounding wall rises to approximately 7 metres on the northeastern side, with the rest standing 2-3 metres high. The structure features the classic broch design of two concentric walls with a stone staircase spiraling between them to the top. Remarkably, Dun Dornaigil's interior has never been archaeologically excavated, making it exceptionally rare among Scotland's 500-plus known brochs. The broch controlled a key route from the coast into the interior of northern Sutherland and is now in the care of Historic Environment Scotland.
