There are two stones at Rockbrook in a field that may have been part of a much longer alignment , perhaps linking up with the stone at Rockbrook 2 (County Dublin). Both are tall, slender monoliths about 1.6m in height.

These are difficult to see from the car due to the wall but hard to miss if on foot. There seem to be two similar stones used as gatepost in the nearby way, marking a now bricked up gatepost.

Alignments or stone rows are groups of standing stones set in straight line. They can occur in any size group from two (usually refered to as a stone pair - see Boherboy (County Dublin)) to ten or more, although anything over four is exceptional (see Castlelanaght (County Cork)).

The function of these is a bit of a mystery, although many do seem to have significant astrological or geographical properties.

The stones making stone pairs often appear to be totally different in shape from each other, often hinting at a male and female partnership.

These stones definitely line up with what I call Rockbrook 2. The north stone is a twisted, slim strange stone some 2m+ tall and the south stone is about 1.8m tall.

Whilst on my way to Larch Hill (County Dublin) with my friends we stopped off not only to admire these twisted stones but to look back on Howth which was now only emerging from the haze.

Whilst driving along the road to get to these stones we noticed a possible seven other stones that may have originated in this alignment. This makes you wonder how long it actually was and if it was just a row or an avenue.

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.
