What an absolute swine to find ... especially at 9 pm on an autumnal evening!!! I got out my trusty OS map and set off. The road up to it is typical farm track/country lane with holes that you could lose a 4x4 in. After I found the hole in the hedge I failed to spot the tomb, so I went back the day after. I can't say it was really worth it, apart from the barbed wire jumping involved ... I always love that.
It is a curious little place consisting of just the side uprights and the capstone . The structure stands about 1.5m tall.
The large rock used to form the roof of a portal tomb or kist.
I was in the area visiting the wedge tombs at Laughanstown (County Dublin) and Shankhill (County Dublin), which are said to be similar in design to this tomb and so I thought I'd make up the threesome.
I also wanted to see if there was any more to this tomb than the two uprights and the roof stone that extend from the hedgerow. Sadly there is not.
One of the most fascinating types of remains left to us by our neolithic ancestors. Enigmatic carvings on rocks, either loose boulders or earth-fast rocks. Designs vary enormously from simple cup marks to amazing spirals, zig-zags, checker-board and lozenge patterns.
No one knows what these symbols once stood for, but many theories exist including star charts, calendars and maps. Many passage tombs are adorned with rock art, both inside the chamber and on the kerb.
Take the R117 from Dublin to Enniskerry. When you come to a Texaco petrol station bear left and take the first left. After about 1.5 km you will reach a farm on the left. Take the road/track beside this and follow it to the t-junction. Turn right and and after about 200m you pass a white house. The tomb is situated on the edge of their garden and the next field.
Although there seems to be this one, fairly poor, tomb on Carrickgollogan it appears that there was once lot more here.
"A History of the County Dublin" By Francis Elrington Ball published in 1902 is a very late printing of an account of Dublin written at the end of the 18th Century.
Book 3, chapter 6 says:
"Within its limits is the mountain of Carrickgollogan (i.e., the rock of Ollaghan).
The objects of archaeological interest are cromlechs and cairns on Carrickgollogan, a rath near Rathmichael, the ruined church and round tower of Rathmichael, "Puck's Castle" (i.e.~ the castle of the pooka), Shanganagh Castle, and Shankill Castle."
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.
