The Rock of Cashel, a medieval stronghold that once served as the seat of Ireland’s kings, is undeniably magnificent. Perched high on an outcrop overlooking lush Tipperary farmland, its round towers, high crosses and 13th-century Gothic cathedral attract a steady stream of visitors. But it’s not the only Irish castle or abbey to draw large crowds. Even off season, there are long queues for internationally recognised sites such as Bunratty, Clonmacnoise, Glendalough, Dunluce, Blarney and Kylemore. Unesco-designated world heritage site Skellig Michael (famous as Luke Skywalker’s island sanctuary in Star Wars) has limited access, and other ancient buildings have been made into five-star hotels.
