This cairn has been razed almost flat and is indistinguishable from the surrounding land.

Drive into Howth via the R105 from Dublin. You will reach a cross roads where the R106 goes north. Turn right here and head south around the island. After passing a cemetery on the right you will come to a left turn. Take this and follow the road around until shortly after a sharp right bend. You should see a track leading over the hill to the left. Park here and follow this track. If you follow this track until 50m or so after it turns north the cairn was on you right.


From here the sun sets down over Bohernabreena , where the mythical Bruiden of Da Derga was on Samhain. Conversely the Beltaine sunrise is over Howth from Bohernabreena. continuing this line to the SE it passes over the tomb on Knockanvinidee, which is the place I first really noticed how Howth is like a focus.

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.
