Visit Notes

Sunday, 3rd February 2002

As you walk down the field towards the two tombs you can see the portal stones standing proud above the protective dry stone wall.

As you get closer you start to see the second stone emerging from behind the other and then when you reach the wall you see the mass of cairn rubble that still surrounds this tomb to a depth of 50cm.

No capstone remains but the two portal stones and a rear jamb are still here to be seen.

These two marvellous tombs should e on everybody's list of places to go.

I remembered this monument to be smaller than it is. For some reason (perhaps due to my poor photos taken on my first visit) I thought that the portal stones here were a lot shorter. It just shows that revisiting a site to refresh your memory is a useful thing to do.

From Dundalk head north up the N1 towards the border. Take the first left after the island where it meets the R173 and then turn right at the next crossroads.Continue for about 600m and take the next right. There is an abandoned cottage on the left about 75m along, park here. To reach the tombs go through the rightmost gate and walk around the edge of the field to the bottom, heading towards the dairy factory. The tombs are just in front of this behind the drystone walls.

About Coordinates Displayed

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.
