This is a fairly unique stone as far as I know, it contains both ogham and runic writing.
Although it is a bit recent in terms of megalithic interest I still think it is a very interesting stone.
Seemingly it was discovered in 1916 within the grounds of Killaloe Catheral.
The inscription in Scandanavian runic reads "Thorgrimr carved this cross" and in Ogham "A blessing on Thorgrimr".
It is now located with in the Protestant Catheral in the town along with a few other great Medieval artifacts.
A high cross, a romanesque door way and a beautiful holy water font.
Im not sure of the opening times of the Catherdal but I would think the best time to find it open is on sundays before and after service which is on at 11.30am.
