Rows of three stones are easily the most common. There seem to be two main types in that: In any one row, the stones are either low enough to see over easily or they are significantly taller than a person.
Axes may be astronomically either uni- or bi-directional but sometimes the rows are deliberately not straight, thus allowing them to indicate additional directions. About half the surveyed sample have lunar axes.
The Ordnance Survey includes Standing Stone Pairs in the Stone Row category but this tradition is not followed here and they are treated separately.
This sample is 27% of all known Cork-Kerry type Stone Rows at time of writing.
