and I quote:
"The monuments were uncovered by experts from NUI, Galway who were working on the most extensive and ambitious geophysical survey ever undertaken in Ireland.
Before the survey began, around 30 monuments had been located. That figure has now been trebled. "
looks like your info is getting a bit out of date ... get out there! In your wellies if you have to ...
like the story though - "as big as Croker Park" - imagine!
