Leac na mBonn (also Seac na m'bun and Leac na hAchainí), #Glencolmcille, Co #Donegal, #TurasCholmcille.
There is a very faint incision of an equal-armed cross inside a circle at the centre of the stone.
I have a completely evidence-free personal theory that this might have once been a coronation stone before the monks showed up.

Stad 15: For most pilgrims, the final stop on the #TurasCholmCille, in the graveyard of St Columba's Church of Ireland, #GlenColmCille. The top third of the cross pillar is broken and usually lies on the ground to the side of the main slab. You can see the dividing line of the break in the image.
