Possible Spiral

>> On a tough sandstone they don't weather much.

It's Wicklow granite. I presume it's the result of some lava glooping bubbling type thing cooling down.

It's a lovely kind of stone - you can make out a faint spiral but . I've never seen one of these monument types, unless from a bus perhaps, in Wales, once.
