Sunday, 12th February 2006

This very rare example of an Irish four-poster stone circle is not marked on the OS map. It is quite easy to find though as it is right next to a lane leading up to a large farmhouse.

The stones are quite short, not exceeding 1m in height. The stone that was once the tallest has broken and the top fragment lies close by. This stone stands at the southwest corner of the setting. The stones are just 3m apart making the whole monument very small and somewhat overpowered by the two large trees that stand just 30m away. These trees appear to be planted in the centre of a ring barrow.

The location of this circle is on a small rise that is surrounded on three sides (south, east and west) by high hills and open to the north. The feeling of being enclosed by these hills is somewhat ruined by the nearby houses and hedges though.

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.
