Bank and ditch fortification
From the notice board near the site
Remaining earthworks
Remaining earthworks of the cairn.
The top of Nevern Castle – a larger bank can be seen ahead this is the motte of the castle – the road is the other side of this.
defensive?
(Picnic benches nearby)
large bank/hill on the left with a ditch on the right. I would assume it was for defensive purposes. A ridge is to the extreme right and just out of the photo.
Ridge which public foot-path occupies (centre) the road is on the horizon. Ditches either side of bank.
View of the public entrance near the road – public footpath goes along a steep ridge (as seen) with ditches either side.
to the extreme left and just out of the photo the topography slopes upwards again; the ditch(es) could then be interpreted as defensive.
