Dun Grugaig

Dun Grugaig is a D-shaped dun, or semi-broch, standing about seven kilometres southeast of Glenelg in the Scottish Highlands. It sits on rugged rising ground on the north bank of the Abhainn a’Ghlaine Bhig, high in Gleann Beag. The site shares the valley with two nearby brochs, Dun Telve and Dun Troddan, but unlike them it occupies a more elevated position. The broch is sometimes called Caisteal Chonil, a name recorded in the 18th century. It should not be confused with another broch, Caisteal Grugaig, a few miles to the north. The fortification has a distinctive D-shaped plan with the straight side facing a steep precipice on the east. Its walls show hollow-wall construction typical of later brochs. The partly lintelled southeast doorway appears to be the main entrance, with a second at the west end. Inside, the structure is filled with rubble, and three doorways open from the inner wallface. Traces of an upper intramural gallery remain visible on the high south wallhead. Visitors reach Dun Grugaig by following the upper reaches of Gleann Beag, where the broch stands apart from the valley floor. The surrounding terrain is rugged and rises steeply around the site. Views extend along the glen and across to the neighbouring brochs. The partly collapsed walls and lintelled entranceways give a sense of the broch’s original form. Despite never being excavated, its well-preserved features offer a clear impression of Iron Age defensive building techniques.
