Cahir Castle, one of the largest castles in Ireland, is located on an island in the River Suir, in Cahir town centre, County Tipperary. It was built from 1142 by Conor O'Brien, Prince of Thomond.
Once the stronghold of the powerful Butler family, the castle retains its impressive keep, tower and much of its original defensive structure. It is one of Ireland's largest and best preserved castles. Check out their modern toilet operation. Oh my!
