Inishmurray is a small island in Donegal Bay off County Sligo. It enjoys a reputation as one of the best-preserved early medieval church sites in Ireland and Europe. The remains are complex and extensive, representing an early Irish monastic community and an important regional pilgrimage centre. There has been no detailed survey of these remains since the 1880s. This new survey and series of excavations by the authors carried out between 1997 and 2000 form the basis for this first sustained interpretative account of Inishmurray. Lavishly illustrated with old and contemporary images, this book does justice to Inishmurray's iconic place in the maritime landscape of Sligo and Donegal Bay.
