Cahir Castle one of the largest castles in Ireland, is sited on an island in the river Suir. It was built in 1142 by Conor O’Brien, Prince of Thomond. Now situated in Cahir town centre, South Tipperary the castle is well preserved and has guided tour and audiovisual shows in multiple languages.
An imposing 13th-15th Century structure, Cahir Castle was skilfully designed by Conor O’Brien to be a state-of-the-art defensive castle. Appearing to grow from the actual rock on which it stands, the castle has been the scene of sieges and bombardments for centuries.
