This is an interesting bullaun stone. In its current incarnation it is being used as an ashtray and stands outside the door of the hotel.
There is a single 30cm diameter bullaun set slightly off centre of the boulder. Next to it is a strange hollow that reminds one of a saddle quern. Could this stone be the one that provides a link between bullauns and quern stones once and for all? The area isn't as smooth as the saddle querns I've seen, so it may just be an odd depression and a coincidence.
This stone came from the Castledermot area.
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.
