Devenish Island

Devenish or Devinish is a lake island in Lower Lough Erne, County Fermanagh, Northern Ireland. Aligned roughly north–south, it is about long and wide.
The island is the site of an early Christian monastery and round tower. It is historically associated with Saint Mo Laisse who is reputed to have founded the monastery in the 6th century. At one point there were up to 1500 religious scholars at Devenish. It possibly belonged to the Culdee order. The settlement, which was raided by Vikings in the 9th century, was burned in 1157. The round tower is 81 feet high with four small windows at the top facing the four cardinal points. Above each window is a finely carved head and a cornice that runs around the top of the tower. There are also examples of 15th century stone crosses on the island.
The island, which is accessible by ferry, is in the civil parish of Devenish. The places to catch a ferry include Trory Point and The Round O, outside Enniskillen. Devenish Island is owned by the Kilravock Christian Trust.
