This has to be one of the finest locations in the whole of Monaghan, spoiled only by the proximity of field hedges, which obscure some of the wonderful panorama. The low, rolling hills surround the low rise upon which this ruinous tomb stands.
The remains of the 3.5m long gallery do have one surprise though. There are some of the the usual wall slabs in situ and a few displaced roof slabs lie, tipped into the centre of the gallery. A fine septal slab just sticks up above the grass, denoting where the gallery was segmented. The surprise though is the presence on three thin stones set perpendicular to the gallery down either side. These appear to be buttress type stone, which are usually only found at the rear of some wedge tombs.
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.
