Well, I finally found the bullaun stone. I actually sttod within 20 paces of it when I visited the church! It's not really surprising that I didn't notice it though as the only visible bullaun is half buried.
This visible bullaun is enormous though at 25cm across and at least the same deep. Apparently, there is another of similar proportions buried beneath the soil.
My instant reaction to this great stone is that it wuld be much better if it was stood up the right way so that it was completely visible and could once again collect water.
This is one of those times when you look at the date on the first visit to this site and think: "Has it really been that long?"
There aren't many suburban bullaun stones around, so I'm rather fond of this one. It is also quite local to me. I wish the effort would be made to reset it properly so that the basin is on the top. The grass around the boulder is starting to consume the basin. It will take quite a while for it to disappear completely, but one day this stone could just look like a big rock.
Sooner or later I'll have to get hold of the key to the church and take a proper look at that.
A small, man made, hemi-spherical depression used as decoration on stones, usually no more than a few centimetres in diameter. They are quite often found with one or more rings around them.

Heading south from Dublin on the N11 take the first left turn after the Blackrock/Leopardstown junction and at the second major crossroads turn left. Take the first left into a housing estate and the church is on your left after just 150m. If you stand with your back to the gate to the church and look slightly to your left you will see a wall and a big boulder. That's the bullaun although the cup itself is on the opposite side.
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.
