Clonkeen

Just outside of the village of Clonbulloge, turn left in the village over the bridge then right after the bridge, follow this road for about 400m and its on the left hand side, is this cute anvil shaped/mushroom standing stone.
Clonbulloge in irish is Cluain Bolg which got me thinking of Fir Bolg so not sure really what it means. The stone seems to be between Clonbulloge and Clonkeen.
