St Molaise (Laisre) founded the monastery at Devenish in the 6thc. Abbots are recorded in the 9th and 10thc. There was a community of Culdees at the site from the 10thc. An Augustinian priory was founded at Devenish c. 1130 (Ware), but it appears that the early monastery continued to function as a separate unit. In 1157 Devenish 'with all its churches' (Annals of Ulster) was burned. The two communities continued after the general suppression, but were apparently dispersed before 1607. Three 18thc. images show the building almost intact (Lowry-Corry 1936, 270-1). According to local tradition, between 1797 and 1803 the building was stripped of cut stone to flag the floor of the new church at Enniskillen, although no evidence of this is now visible in the latter structure.
