Like the graveyard at Bobsville (County Meath) this graveyard is built on a mound. It can be clearly seen in the centre of a large flat field on the lefthand side of the road that heads west from Colbinstown.
In Borlase's Dolmens of Ireland (1897) this site is the only entry for County Kildare in the rather limited gazetteer section in Volume II, so I was very surprised to realise that I'd not heard of it anywhere else. In his description this mound has a thin slab blocking a passage, but the passage certainly isn't visible today, although there are two slabs on the east and west sides.
There are many authentic-looking standing stones among the gravestones and some very new looking ones ... especially the ones with scratched in ogham. On the east side of the mound there is a 10m stretch of kerb visible and another length on the northeast side.
To tie in the day I was able to see the clump of tree on the top of Brewel Hill to the north that surround the stone circle there. This just wet my appetite for vsiting Brewel Hill next.
A kerb is a ring of stones placed around the perimeter of a burial mound or cairn. It basically serves the purpose of a retaining wall to keep the cairn or earth in place. Kerbs are usually associated with passage tombs, but do occur on court tombs and wedge tombs too.
Sometimes on passage tombs the stones can bear decoration, such as at Newgrange (County Meath).

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.
