Comparative images of the possible monument at Ballyboy Lake, in the Boyne Valley near Dowth
This is a series of images of the possible archaeological feature at Ballyboy Lake, near Dowth, in the Boyne Valley, as seen on Google Earth, Flash Earth and Ordnance Survey imagery. The circular feature may just be an optical peculiarity, or a vegetation feature. It certainly warrants further investigation. Might it be a crannóg - a lake dwelling, of which there are 1,200 known examples in Ireland? I have brought this feature to the attention of an archaeologist, who will hopefully be able to ascertain whether this might be a newly discovered archaeological monument. Of course, there's always the possibility that it's nothing . . . but we will wait and see.
