When I first saw a picture of this in the Cavan Archaeological Inventory I was smitten. What a weird design, what a lovely tomb, what a lovely setting. Well, it is the first two still, but as for the lovely setting - that's gone now. This enigmatic little tomb now sits in someone's driveway!
The ground appears to have been lowered around it (don't know how stable it is now) and the attractive use of weed killer around its base looks beautiful Ö I don't think so!
The tomb almost seems like a cross over. It does have two portal stones but these extend beyond the chamber and do not support the roof stone, which just sits on the polygonal chamber instead.
Don't avoid this tomb because of the imposition of this horrible house - go and see it - go and show the people who built the house that they have a public curio in their garden and loads of people are going to be pointing cameras at their house.
Apparently the reason this tomb looks so odd is because it was messed about with in the 1900s. A bullock became trapped within and a side stone was removed to facilitate its removal. When this was done the capstone slipped from the portal stones. A local priest made them replace the side stone but the capstone remained out of place. (source: Weir)
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.
