Blackstairs

This standing stone forms part of the field boundary. However I do think it is in the original position because it seems well inbedded into the ground.
It is wider at the base and at least 2m. All around it to the north east and west are low hills. However to the south-west what I think is the hill of Knockgrean/Knocksefin rises up in Limerick and my feeling is that is placed in reference to these.
