"Do you happen to know what was found at the Mesolithic site up the road?"
I do indeed. They found a few circles suggestive of huts, a few hundred flint and chert flakes, and three cremations. This is possibly one of the most significant mesolithic sites in Ireland, after Mount Sandel, in that it gives good solid evidence for what the these people were doing with their dead. Before this, all we had was a few remains from a midden, and some bones from a cave. Now, we know they took the time, and had the expertise, to cremate the dead, and bury the ashes. Not only that, but the site also revealed polished stone axes, one of which was recovered from a pit containing a cremation, and a substantial post hole. This suggests that the buried cremations were marked above ground with markers. These may or may not have been decorated.
It also pushes the date for polished stone axes way back into the earlier mesolithic, so all in all, a very inportant site.
