Visit Notes

Sunday, 3rd February 2002

Well, the actual henge on the OS map is not really there, but there is a very impressive henge bank that is almost 1.5m tall and would have been some 80 or so in diameter.

There is an eventing course that crosses it now.

Directions

From Naul take the R108 north and after about 1.6km turn left. Go past Fourknocks to the end of the lane and turn right. Take the right fork at the next junction and then right again at thenext crossroads. The henge should be about 150m along on the right, look out for the mound.

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.
