This is a most unusual bullaun stone. The single bullaun is about 30cm across and quite shallow. Nothing too strange there, but the stone it is in is rectangular. To add to the oddness the bullaun is at one end of the stone, so it's hard to fathom out why it was cut this way. It seems obvious that it was cut from a larger stone, but why so weirdly?
The stone can be found in the cemetery at the base of one of the church walls close to some rubble that has fallen from it. Hopefully, it won't become hidden underneath any more that might fall. I don't think it will as the graveyard seems to be well-tended.
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.
