This stone has been moved from elsewhere to its current location. The tall, pointed boulder must have been earthfast at one time.
It now stands below a huge beech tree in the grounds of a country house. It is oddly surrounded by a modern stone circle formed from tall, square-sectioned granite pillars.
The stone has a single conical bullaun at its apex, which is 20-25cm diameter and around 30cm deep. Conical bullauns seem to be very popular in County Carlow - I'm not sure that they should really be classed as bullauns and think that they might have performed a different function to the more common hemispherical ones.
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.
