When you visit these forest embedded tombs you expect two things -
1) To take ages to find them.
2) That you'll be disappointed when you do.
However, with this tomb neither points apply. Both courts and chambers are in fairly good order. Both are certainly good enough to enable you to see the size and layout of each, although the northernmost one is by far the better of the two.
The north court is 4m wide by 3m deep leading to a 4m long chamber which is split into two section by a low jamb. The southernmost court and chamber is about the same dimensions. There is amazingly a 12m gap between the backs of the two chambers making the whole structure at least 26m long and 8m wide. There is little or no trace of the cairn and no roof stones survive.
The sylvan glade that this tomb now sits in does actually add to the enjoyment of this site and makes a visit here quite good. Perhaps the bright dazzling sun filtering down through the canopy helped.
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.
