This monastic complex, perched since about the 7th century on the steep sides of the rocky island of Skellig Michael, some 12 km off the coast of south-west Ireland, illustrates the very spartan existence of the first Irish Christians. Since the extreme remoteness of Skellig Michael has until recently discouraged visitors, the site is exceptionally well preserved.
