This is a very unusual Bullaun Stone as far as I can see.
The stone itself must be about 1.25m high by about 1.75m long and is probably big enough to be a standing stone in its own right.
The depth of the bowl is about 600mm deep, I presume that must be a lot for a bullaun.
Also there is what looks like a few cup marks on one side. They may be natural but who knows?
There is a church and holy well about 200m away from here. However to put it in context, it is also in an area rich with older sites such as standing stones (a holed one at Inch) and the hillfort at Knockroe and the unusual features on Luddenmore.
