We crossed the field to this stone, not knowing that there is a path along the reservoir to the other stone down by the lakeside. This is the better of the two at Knocktemple, the basin cut into the slope of the stone giving it one deep arc and one shallow. It's bang in the middle of the field, just west of the old church site.
The first signed bullaun stone that I've seen – I'm guessing that this was dragged here to its current location before they drowned the valley for the reservoir. I've seen shots of this semi-submerged, but we were here after a fairly decent summer and the lake was about 5 metres away.
I was searching for a bullaun stone south of Roundwood recently and the woman of the house told me of this stone – seems it's well known in the locality and has 'offerings' in the basin. the stone itself is quite large, a metre-and-a-half long, by a metre high and three-quarters of a metre wide. The basin is, fairly typically, set off centre towards the west end of the stone.
