Nestled among the pine plantation forest and mobile phone aerials this is a sad sight.
The mound is bracken covered, about 10m in diameter and 3m tall, with a small path leading up to the top and on the west side you can make out where the entrance would have been.
On climbing to the top you can see that the roof has collapsed and you can, after brushing aside some vegetation, see the remains of the roof corbelling. Like Seefin Hill (County Wicklow) the roof seems to have comprised of red quartz.
If the aerials were not here this would be a beautiful spot.
A visit here now is well worth it because a lot of the trees have been felled around the mound. You can now appreciate why the site may have been chosen. You can now look west out across the plains and down onto Athgoe Hill.
To the west of the tomb are two large boulders, which may be displace kerb stones or they may be stones taken from the roof of the chamber when it was opened up. Having seen the dip in the top of the mound again I am sure that it was opened up at some time.
The best approach is to park at the entrance to a small track O 014 225 and walk up the track. Take the first right hand junction and follow the track around until you reach the radio masts. The tomb is situated to the left of the track behind what looks like an airfield control tower.
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.
