So many people drive around the base of this busy hill without realising what is sitting on the top. The only place that it is really visible from is Crom Castle across the valley to the north east. It too offers a good view of Crom Castle.
It is marked on the RoI OS maps as a cairn, but no cairn survives. What does survive is the astoundingly huge kerb that is 35m in diameter, consists of 90+ stones some of which approach 2m in height.
The kerb is almost continuous and in the centre are the remains of the passage tomb that would have been inside the cairn. When the cairn was in place it would have been very impressive indeed.
The views from the hill top are great taking in three counties and as mentioned offering good views of Crom Castle.
I was left quite speechless by the sheer scale of the stones used in this kerb ñ they easily rival the size of those used at Newgrange and Knowth.
This is a wonderful place that is little known.
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.
