Visit Notes

Sunday, 15th September 2002

I had known of this barrow for some time, but I never expectd to ever see anything here, but I should have looked by earlier, especially as it is right by the roadside. So close in fact that the road cuts a little piece off it.

It is around 12m in diameter with a 1m wide fosse and external bank. This is in surprisingly good condition and well worth a look.

A fosse is a man made trench that is often associated with a bank. Fossse can be used to refer to a dyke, the circular trench around some barrows or the trench dug around a ring fort for defensive purposes.

With the weather being so good and the sun being quite low still I'd hoped to get some good definition on the bank and fosse, but by the time I had reached the site the sun had risen and gone behind the only bit of cloud around.

However, the weather was a lot better than it was on my 2002 visit! and better than my revisit in 2006 (not mentioned here, because the weather was so bad). Today I could enjoy the wondeful views down the Bohernabreena Valley and all the way out to Howth and Lambay Island. Wonderful.

The new road layout past the barrow doesn't seem to have impacted further on the monument.

Follow the R114 out of Dublin and take the third right after Oldbawn. Be careful this is a nasty turn that doubles back on itself on a blind bend. The barrow is just 20m along this road on the left.

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.
