A British fortress on Barra-hill in Aberdeenshire.. deserves notice. It is built in an elliptical form; and the ramparts were partly composed of stones, having a large ditch that occupies the summit of the hill, which as it is about two hundred feet above the vale, overlooks the low ground between it and the mountain of Benachie. It was surrounded by three lines of circumvallation. Facing the west the hill rises very steeply; and the middle line is interrupted by rocks; while the only access to the fort is on the eastern side where the ascent is easy; and at this part the entry to the fort is perfectly obvious.
This Caledonian hill-fort is now called by the tradition of the country, Cummin’s Camp, from the defeat which the Earl of Buchan there sustained, when attacked by the gallant Bruce.

Info, Rhiannon, I think you'd find helpful and interesting is on the Barra 1308 link.
Jock o Bennachie nust have been in a foul mood as he is mentioned in both the links I've put up on the Gouk Stone, Bennachie page. And now the Tap O Noth is involved as well (Barra link).
