Eigg, Corragan Mor

RCAHMS surveyed the fort at Corragan Mor on 12 October 2002 with plane-table and self-reducing alidade at a scale of 1:500. The plan was later used as the basis of an illustration that was published in 2016 (Hunter, fig. 3.18).

This small fortification occupies a craggy hillock that forms a pinnacle rising out of the top of a cone of talus at the foot of the cliffs on the E side of Eigg. The defences comprise a single wall dawn in a rough square around the outcrops, though even the scatter of stones that marks its course on the N and NE peters out on the SE; elsewhere on the NW and SW, around the margins of the terrace that forms the only occupiable space on the hillock, the wall forms a band of rubble about 2.5m in thickness along which a few inner and outer facing-stones are visible. The interior measures about 34m square (0.11ha), but two thirds of this is taken up by the boss of rock that gives the hillock its distinctive profile. The entrance is probably on the SE.
