Garmna island church

Gorumna (Irish: Garmna) is an island on the west coast of Ireland, forming part of County Galway.

Geography

Gorumna Island is linked with the mainland through the Béal an Daingin Bridge. Gorumna properly consists of three individual islands in close proximity, Lettermullen, Teeranea (Irish: Tír an Fhia) and Lettermore.

Geology

Gorumna Island is mostly underlain by intrusive Devonian-aged Galway Granite that formed from crustal melting as a result of the Caledonian Orogeny in the late Silurian. Its southern tip also includes Ordovician-aged bedrock of sedimentary marine rocks and basalt.
