Depite there not being a lot to see here I found this tomb of great interest. As you approach it appears to be a low mound, about 1m high, with a flat top, from which a few stones poke out. When you get up close you can see that the chamber is a very curious figure of eight shape. Quite extraordinary.

_The figure of eight chamber here is thought to represent two stages, the northern-most chamber being the original. This makes sense as this occupies the centre of the boulder circle. The circle has being partial robbed away and it is represented now by just 14 stones.
To me it gives the impression that the second chamber was actually formed by closing the passage to the central tomb, but the excavations obviously didn't point to this being a correct theory. If it was true then the passage would have pointed straight at the area now occupied by tomb 51 - Listoghil.

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. |
