Cocromroe Cistercian Abbey Corcomroe Cistercian abbey is situated in a fertile valley in the unique limestone landscape of the Burren, Co. Clare. Although no sources refer to its foundation, it is probable that the monastery was founded by Domhnall Mór O’Brien c. 1194 as part of his policy of patronage of the church and strengthening his rule in the region.
Ennis Franciscan Friary Ennis Franciscan friary was built on an island at a point where the river Fergus divides. This island is now incorporated into the streetscape of the modern town but remnants of the medieval settlement are evident. Apart from the friary, traces of the O’Brien medieval residence and late medieval houses are scattered throughout the town and it is clear that the friary was deliberately located at a crossing over the river into the settlement. It also benefited from river fisheries. The original O’Brien founder of the friary is unknown – it may have been Donnchadh O’Brien, king of Thomond (d. 1242) but no records survive.
