I think this is the largest of the circles here. It's certainly close to being the largest, but it is difficult to be sure.
This is a 7m diameter ring of low stones, protruding just 20-30cm above the peat. You can make out at least one tangential stone row that runs in a southerly direction. This, also, only just pokes out above the peat.
These circles are very similar to those at Beaghmore (County Tyrone) and excavations would clear them up beautifully and make them so much easier to understand. I hope the money comes forward to do this at some point, as I'm sure there's more in the vicinity.

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. |
