Monument record MHG11938 - Rubh Na Griosaich

NC46NW 4 4415 6599.
Over a natural arch is a causeway defended by two lines of boulders. On the promontory are two buildings - rectangular. The SW edge of the promontory may have been delimited by a wall.
Info from Dr C S Sandeman, Durness, 14 March 1967.

The promontory is approached by a natural causeway about 15ft wide over a natural arch. At W end six boulders have been set upright in earth. 16 feet to E of boulders the causeway is 9ft wide. On the promontory is a sub-rectangular structure, with a rectangular structure about 33ft to E.
Info contained in letter and field notes from K Reid to OS 25 September 1978.

A cliff-girt promontory accessible from the landward side by a natural causeway over a natural arch. A line of earthfast angular boulders block the approach, and on the causeway itself an embedded, transverse slab may indicate a further blocking wall. On the promontory are footings of a rectangular structure measuring an estimated 8.5m by 5.0m within a wall 1.2m thick; a short distance to the E among rock outcrops are traces of a small, possibly circular structure. Along the SW side of the promontory and round the NW, stone showing in an eroded scarp indicates a skirting wall. It is unlikely that this is a fort in view of vulnerability from NE where the cliffs give way to shelving rock. This could well be a monastic settlement and it may not be coincidental that a monastic site (NC46NW 5) is clearly viewed to W.
