Sunday, 4th January 2004

This tomb seems quite ruined when you first approach, but it does get better when you climb the drumlin that it sits on. The court is missing completely, but the entrance jambs are still in situ. The east facing entrance is a little bit confusing at first until you realise that the lintel has fallen into the gap. Resting against the back of these three stones is a massive roof stone, the base of which is in the gallery . This is over 2m square.

The stones forming the 5m long gallery seems oddly out of proportion with the entrance, because they are all very low. The gallery is segmented into two chambers by small jambs.

To the rear of the gallery are two subsidiary chambers set into either side of what would have been the cairn , none of which remain. These sub-chambers are 1.2m wide and 1.5m deep, with a 1m gap between their backstones.

Two stones place either side of a gallery, opposite each other, but not touching so as to leave a gap, that are used to segment it into smaller chambers.

A low stone used to de-lineate the divisions of a gallery. Sill stones fill the width of the space, but do not reach the roof.

A cairn is a large pile of stones, quite often (but not always) containing a burial. Sometimes they have a kerb around the base.

Most cairns are hemi-spherical (like half a football), but the piles of stones used to cover wedge tombs, court tombs and portal tombs are also called cairns. When associated with these types of monument they are not always round, but sometimes rectangular or trapezoidal.

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.
