This is a really tricky one to spot, but well worth the effort. I was told that it was built into a gateway, but in fact it is incorporated into the base of a wall near to the gate.
The stone is 80cm by 40cm and is entirely covered in deep, clear cupmarks. At the bottom left corner there is a cup mark surrounded by two rings. There are over 15 cupmarks in all on this great piece of stone and the position of the stone in the wall has obviously provided some protection to weathering and to see the cupmarks so deep (some are 3cm deep) is wonderful and makes you think how wonderful some of the more weathered examples must have once looked.
The photos I have of this stone don't really do it justice, so now that I occasionally manage to take a good side-flash photo of rock art I thought it would be a good idea to stop by and try to take some half-descent images. I was surprised by the outcome, because I managed to see some rings around some of the cupmarks that I hadn't seen previously.
From Goresbridge head east along the R702. Where the main road takes a sharp right continue straight on. 300m along this road take the righthand fork. Continue to the end of the road. Turn left up the R705 and then right after 300m. Continue until you reach a crossroads. Carry straight on and then take the right fork. After 500m you will see a farmyard on the left. The rockart is in the wall at the next gateway.
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.
