The Boyle Abbey (Mainistir na Búille) is one of the most well preserved, early monastic ruins and…read moreis part of the National Irish Historical Registry. Boyle Abbey was part of the early Church's' effort at reform, by introducing the Cistercian monastic order from France. The early Cistercians found life difficult in Connacht and after several failed attempts, settled at Boyle in 1161. The Abbey was believed to be consecrated in 1218. The cloister did survive, just barely after two defilements, first by the Elizabethans in 1592 and then later, by Oliver Cromwell Model Army's sieged of 1645. If you want more information, see: http://www.heritageireland.ie/en/west/boyleabbey/ The grounds are well kept and are easy to walk. At the entrance there is a printed map showing what was believed to be the early structures. Expect to spend 30 to 45 minutes exploring the ruins. By the way, if you do not have an OPW Card, the admission Fees are €4 for Adults, €3 for Seniors, €2 for Students and Children. Again, I would highly recommend buying an OPW Card for €40 for Adults and €30 for Seniors. It's a bargain. See: http://www.heritageireland.ie/en/info/heritagecards/
