Just down a little path from the well at St. Cumin's Well (County Mayo) is an overgrown churchyard. Considering how well-kept the well and mass station is I was appalled to see how bad the churchyard was.
The church itself is built of cyclopean blocks of stone, with a lovely round-topped doorway in the west wall. There is a blocked up opening in the south wall, which was presumably an earlier door. There is a single round-topped window in the south wall and one in the east wall. The north wall is plain.
The church is not aligned east-west, but more towards the ESE. At 2 o'clock the sun wasn't shining on the west wall of the church.
In the graveyard are two slender standing stones about 1.8m tall. Between these are several low slabs in a line. This is said to be the burial place of St. Cumin. After pulling back the grass around the tallest of the little slabs I was surprised to find that it was a cross slab. The design is quite intricately carved in false relief and is quite hard to explain, but it is basically a cross with expanded terminals in an oval. There are also two 'sun' motifs above this and a flower design below it.

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.
