Over looking St. Mogue's Well and the old abbey is this church ruin. It is said that it did not appear in a document detailing the buildings of Ferns made in 1537 and so the church must have been built sometime after that date.
Despite its late construction it does have a couple of interesting windows. One, in the south wall is a nice round-headed Romanesque window and the other is the east gable windows which appear to be Gothic. The Romanesque window must have come from another church in the area and the Gothic windows are thought to have been robbed from the abbey.
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.
