This cross is lovely. It's big, it's rough and it's very tactile. There is no decoration on it, but it is made from a red/brown sandstone that has veins of a harder stone running through it. This has cause the cross to erode unevenly so that the veins are raised.
The cross stands over 2.5m tall and offers wonderful views across the bay. The church here is no more than a shell, but this and its remote location hint at the age of this site as a Christian settlement.
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.
