...the rocks are in Ireland in Co Sligo. They are located in the middle of a woods that was planted fro commercial use and were discovered during felling operations. They vary in size and shape as you can see from the attached pictures and some are in very close proximity.They are in a few fields in the corner of a townland just beside an old farmhouse that possibly dates fromt the early 1800's. Its a relatively undisturbed area as the woods makes it quite difficult for walking as does the terrain which is in the middle of a glacial valley so there would have been numerous rock deposits around.
I've no problem with you publishin the pictures. Might even give us some answers. They arent the best quality because the lightin was very poor and with the trees you caould only get individual close ups as opposed to a picture of the whole scene.
I'd be grateful of any suggestions or any similiar structures you've come across and their potential purpose.
