(NH 5669 9098) An Dun (NR) (Supposed Pictish Fort)
OS 6"map, Ross-shire, 2nd ed., (1907).

Classified as a broch by Graham and Watson, and said, by Watson, to be known as 'Carn Liath'.
A Graham 1949; W J Watson 1904.

The remains of broch with outworks, known locally as An Dun, situated in strong defensive position on promontory between River Carron and Allt Dounie.
Broch survives as overgrown mound with central depression which has been partially cleared revealing intermittent traces of the inner wall face which suggest an internal diameter of c10.5m. No other measurements can be determined. A gap in SE with a displaced lintel stone within, probably denotes entrance, but no details are evident. It is defended in N, S, and W by steep slopes of the promontory, and in E by two substantial ramparts drawn across neck of the promontory, each fronted by a ditch c8m wide, the outermost being rock-cut at its S end. The outer rampart appears to have been revetted internally with dressed stones. The entrance has probably been in S where defences end on the natural slopes. A bank, showing set stones, occurs outside these defences and is probably another mutilated rampart. The broch and outworks are clearly contemporary.
