About Inishmurray

Inishmurray is an uninhabited island off the northwest coast of County Sligo, Ireland, notable for its well-preserved early medieval monastic remains. The island contains substantial stone ecclesiastical remains and domestic structures clustered within a defended enclosure.

The visible remains include an enclosure wall, church foundations, beehive-type stone huts, grave slabs, and other associated features that reflect several phases of activity from the early medieval period onward. The site is an important example of insular monastic settlement in Ireland.

The island retained a small resident population into the 20th century but is now uninhabited; visitor landings and guided visits occur seasonally when weather and sea conditions permit.

Inishmurray sits offshore from County Sligo and is visited by boat from local piers on the mainland.

  • Access and safety: Landing on the island is weather dependent and often requires an experienced local boat operator; visits are commonly restricted to the summer months.
  • Dating and significance: The archaeological remains date to the early medieval period, with material and structural evidence from roughly the 6th to the 12th centuries, and later small-scale habitation until the mid 20th century.

What to See#

  • Monastic enclosure: A compact monastic enclosure with stone walls and the foundations of churches and ancillary buildings that form the core of the early Christian settlement.
  • Beehive huts and burial sites: Clusters of stone beehive-style huts and grave slabs that illustrate domestic and funerary practices on the island from the early medieval period onward.
