Monument record MHG624 - An Dun Promontory Fort

Dun (NAT) OS 6" map, (1965)

Fort, An Dun, Borgue: Situated on coast near Borgue is a remarkable rock peninsula, connected to mainland by a natural bridge at a much lower level than either, and about 6ft wide at the top. The peninsula is a hog-backed ridge lying parallel to the coast line, and sloping steeply to precipitous cliffs on either side, but with the longer slope to seaward, and rising in elevation towards its S end. Only at highest point is there any level ground and there, only an area about 20ft square. Along ridge facing the bridge is exposed a section of wall, and there are slight indications of its continuation to S.
RCAHMS 1911.

Generally as described by RCAHMS, but wall mentioned would appear to be natural rock strata exposed by considerable erosion which has taken place. There are no traces of any other features of antiquity on this rock.

An Dun is a knife-edged promontory connected by a narrow natural causeway to the land. There is no evidence either on the promontory or causeway of walling; the wall noted by the RCAHMS appears to be natural rock strata. There are no visible remains to suggest a fort.
