Somewhere near the girl's dorms, I'll bet.
Nearly all the ancient kings are buried at Iona. As for Kilmartin Glen..I dont know, but, that was the area where the ancient kings ruled. These were the Picts, and the Scotty Irish kicked them out, eventually. The Picts simply vanished over a very short time. Lots of grave slabs over there that are really interesting to look at. Especially at Kilmartin.
