Devenish Island is one of the finest monastic sites in all of Northern Ireland and was established between 500-600 A.D. In 1300 A.D. the original church was extended, and later a Maguire chapel was added to the south with several different 17th century heraldic slabs.

On Devenish Island is a round tower that is estimated to have been built between 1100-1200 A.D. The round tower is about 100ft tall and was used to escape Vikings and other attackers using a system of internal ladders. During an attack... the church scriptures and valuables were rushed inside the tower for protection.
Devenish became a centre for religious scholarship and learning. The community became very successful even though it was raided by Vikings in 837 and burned in 1157.more to come...
