This standing stone Id definitely put in the unknown gems of Ireland. It is a huge stone way over 2.5m high and it must surely be the highest in these parts. It is waffer thin about 200mm.
It is kinda knife shaped with the handle dug into the ground.
To find it turn right just after Hospital (going towards limerick) and follow the road. It is in a field next to a sign for a vets practice.
The pics I have arent great but there is a big hill to the which it seems to addressing as they say to the top right of the first photo.
This would be roughly west from it.
