The monastery on Devenish Island was founded in the 6th by St. Molaisc (d AD 570), much still remains including a round tower which probably dates from the 12th century, church, graveyard, Celtic cross and a stone coffin, the monastery grew in importance and by the 8th century it was one of the most important in Ireland.

The Vikings raided it in 836. The churches were burnt in 1157. A local chieftains son was killed in the round tower in 1176 apparently by a kinsman. Devenish retained its importance until the early 1600's and was used until 1824 when 19 people were drowned when a boat carrying a coffin overturned in a winter squall.
