This cross slab is beautifully decorated on both sides with a similar design, although you do need good light to see the pattern clearly - either side of noon on a sunny day would be good.
The pattern consists of a the outline of a flared cross (there's probably a proper name for this type of cross), the centre of which is filled with a nice Celtic know pattern. There is a border around the edge of the slab.
The slab is about 1.2m tall and stands next to a broken cross pillar (see Inishkeel (County Donegal)).
Note: Inishkeel can be accessed at low tide by walking across 800m of exposed beach, but do check the lengths of the low tide before crossing over.
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.
