Duntryleague in Limerick. According to a passage in the Book of Lismore, a dun or palace was built here for Cormac Cas, son of Olioll Olum (see Connello); and his bed was supported by three liagáns or pillar stones, from which the place was called Dun-tri-liag, the fortress of the three liags or pillar stones.
