The OS map is somewhat confusing here: it shows five crosses which have 'Chambered Graves', 'Standing Stones' and 'Stone Circle' written in the general area. I really didn't know what to expect.
After sitting and chatting for a while with the old lady at the new bungalow I set off into the rain to see what I could find. The site of this complex occupies the southern high ground and the top of a northwest facing low valley.
This tomb is the largest of the ones I located before giving up. The rain was so heavy I couldn't see a thing!
The gallery of this tomb is over 5m long and around 1.5m wide. It faces northwest along the little valley below (the valley floor is only 20m below the high ground at the sides.) At the front there are two large facia stones in place either side of the entrance. There is a portico in front of the main gallery. The entrance to the gallery is quite unusual: two portal-like stones form a narrow entrance into the gallery, which is blocked by a septal slab set behind them.
The gallery is segmented into two chamber by another septal slab. This, the backstone and the walls are buried quite deeply into the remain of the cairn . Parts of the double walling can also be seen.
In wedge tombs and court tombs the burial compartment is known as a gallery and collectively wedge and court tombs are called classified as 'gallery graves'. This is because the inner area is long and narrow, i.e. bascially rectangular, in plan.
In court tombs the gallery is usually divided into two or more chambers by jambs. Wedge tombs are segmented by sill stones, as are a few court tombs.
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.
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.
