Poulnabrone dolmen megalithic tomb, Burren, County Clare, Munster, Republic of Ireland (Eire), EuropeThe Burren (from Irish: Boireann, meaning - great rock) is a unique karst landscape in northwest County Clare, Ireland. The limestone area measures 300 square kilometres and is roughly enclosed within the circle comprised by the villages Ballyvaughan, Kinvarra, Gort, Corrofin, Kilfenora, Lisdoonvarna and the Black Head lighthouse. The definitive article (ie "The" Burren) has only been added to the name by academics in the last few decades as it has always been traditionally called Boireann or Boirinn in Irish and Burren in English.
