Looking for something more subdued? Head to southeast Ireland. The towering Rock of Cashel dominates the skyline and tourists' attention, but nearby Hore Abbey is equally beguiling. The crumbling 13th-century ruin sits idle on farm land, entertaining dairy cows and the occasional wanderer. If you're looking for a peaceful pasture to absorb the world's end, this is it.
