Visitors have been leaving coins in cracks at the Giant's Causeway in Northern Ireland AFP Northern Ireland's Giant Causeway draws close to one million visitors a year but their habit of wedging tiny coins in cracks between the rocks -- to bring love or luck -- is damaging the world-famous wonder. Now authorities are urging tourists to keep their coins in their pockets to preserve the spectacular landscape. Some 40,000 columns mark the causeway, Northern Ireland's first UNESCO World Heritage Site.
