The Burren (Irish: Boireann, meaning “great rock”) is a karst landscape in County Clare, Ireland. It measures approximately 250 square kilometres and is enclosed roughly within the circle made by the villages of Ballyvaughan, Kinvara, Tubber, Corofin, Kilfenora and Lisdoonvarna.
The Burren National Park is one of six National Parks in Ireland and the smallest in size (15 km2).The Burren National Park Visitor Centre is located on Church Street in Corofin, County Clare, Ireland.
The Burren area formed part of the territory of Corco Modhruadh, meaning “seed or people of Modhruadh” which was coextensive with the diocese of Kilfenora. At some point around the 12th century, the territory was divided in two: Corco Modhruadh Iartharach (“Western Corcomroe”) and Corco Modhruadh Oirthearach (“Eastern Corcomroe”) also known as Boireann which in the late 16th century became the English administrative baronies of Corcomroe and Burren respectively. The O’Loughlin (Ó Lochlainn) clan ruled Boireann down to the mid-17th century from their chief residence at Gragans Castle (towerhouse not the house of the same name). The chief of the family was known in later times as the ‘Prince of Burren’ and clan members were buried in the family tomb near the altar of Corcomroe Abbey. Their kinsmen the O’Connor (Ó Conchubhair) clan ruled Corco Modhruadh Iartharach from Dough Castle near Liscannor. The villages and towns found within the medieval territory of Boireann include Lisdoonvarna, Ballyvaughan, New Quay / Burrin (Burren), Noughaval, Bealaclugga (Bellharbour), Carron and Fanore / Craggagh.
Burren is rich with historical and archaeological sites. There are more than 90 megalithic tombs in the area, portal dolmens (including Poulnabrone dolmen), a Celtic high cross in the village of Kilfenora, and a number of ring forts – among them the triple ring fort Cahercommaun on the edge of an inland cliff, and the exceptionally well-preserved Caherconnell Stone Fort. Corcomroe Abbey is one of the area’s main scenic attractions.
