There are a number of rock art sites on Doagh Island (Magheranaul Townland) but they were rather difficult to find.
You can find the rocks where you would expect the rock art to be but many were only partly visible through the turf. Light turf clearing showed the extent of the cover was more than I was prepared to deal with.
However, I did find one interesting motif. A cup with a tail surrounded by other radiating lines (at C4322849720 on the GPS) and another probable motif some 5 - 10m to the W of it.
Also looked at some rocks in the area around C426500 which are recorded as containing rock art. One at C4281849955 looked a possible candidate but was heavily weathered if it contained anything at all. In the flat light of the day, the photos taken here do not reveal anything.
Magheranaul (Cup and Ring Marks / Rock Art) — Fieldnotes
After scouring the fields for the rock art locations on archaeology.ie for a couple of hours I slowly accepted that these panels have either become turf covered, or, more alarmingly, been blown up with dynamite like many of the outcrops on the hillside obviously have been over the past few years.
The blown up outcrops in the first field from the road have not been cleared and the remaining stone still litters the hill, this is probably not a good sign since it seems to suggest clearance or building stone was not the reason for using dynamite.
I only found these carvings after a lot of staring at outcrop. There's definite parallel grooves enclosed by lines but these are hugely weathered now and difficult to bring out in full. I also spotted a single cup surrounded by an almond or 'eye' shaped ring on the same outcrop.
