I hadn't held much hope of finding this stone and as I approached the location I had even less, because there was a modern house right where it should be. I parked up and looked over a few hedgerows and decided that it must be lost. Walking back to the car a large rock in the driveway of the new house caught my eye. Could it be?
Yes, it could! The stone looks as if it was once earthfast - it's over 1m tall now that it's freestanding. There is a fully-formed bullaun at one end of the upper surface and a shallow dip towards the other. A small channel leads from the full bullaun to the outer edge of the stone.
This is a nice example and a very nice thing to have as the centrepiece of your driveway.

This is an explanation of (and a bit of a disclaimer for) the coordinates I provide.
Where a GPS figure is given this is the master for all other coordinates. According to my Garmin these are quite accurate.
Where there is no GPS figure the 6 figure grid reference is master for the others. This may not be very accurate as it could have come from the OS maps and could have been read by eye. Consequently, all other cordinates are going to have inaccuracies.
The calculation of Longitude and Latitude uses an algorithm that is not 100% accurate. The long/lat figures are used as a basis for calculating the UTM & ITM coordinates. Consequently, UTM & ITM coordinates are slightly out.
UTM is a global coordinate system - Universal Transverse Mercator - that is at the core of the GPS system.
ITM is the new coordinate system - Irish Transverse Mercator - that is more accurate and more GPS friendly than the Irish Grid Reference system. This will be used on the next generation of Irish OS maps.
