For some reason this is not on the OS maps, but it is so well worth finding. It must be one of the cutest tombs around. Other pictures of this site on the web appear to show a much different dolmen and so this one may have been rebuilt at some point.
It sits prettily beneath a tree and is a very low structure with much of its cairn intact (or is that field clearance?).
As pretty has they come. But probably not too genuine in its appearance.
A cairn is a large pile of stones, quite often (but not always) containing a burial. Sometimes they have a kerb around the base.
Most cairns are hemi-spherical (like half a football), but the piles of stones used to cover wedge tombs, court tombs and portal tombs are also called cairns. When associated with these types of monument they are not always round, but sometimes rectangular or trapezoidal.
As this was one of the first places I visited in my neighbourhood I decided to pay another visit and get some spring time pictures.
From Enniskerry follow the Glencree Road. After just under 1 km you will come to a closed village shop on the left. Park here. Walk down the road away from Enniskerry until you see a track on the opposite side of the road next to a ruined gatehouse. The dolmen is about 300m down this track.
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.
