Dun Grugaig

Dun Grugaig is a D-shaped Iron Age dun, or "semi-broch," in Gleann Beag near Glenelg, Highland Scotland. Measuring roughly 47 by 38 feet with walls 14 feet thick surviving to about 4 metres high, it features mural chambers, a scarcement ledge, and a blocked entrance passage with door checks and bar hole. Located on rugged rising ground above the Abhainn a'Ghlaine Bhig, it sits in the same valley as the well-preserved brochs of Dun Telve and Dun Troddan. The site has not been excavated, though it was first recorded by Alexander Gordon in 1720 as 'Castle Chonil'. Its hollow-wall construction is considered characteristic of proto-broch design.
