  • Tourist coins pose giant problem at N. Ireland's famous causeway site

Visitors are being urged to stop leaving coins in cracks at the Giant's Causeway in Northern Ireland to prevent damage to the stones at the world-famous tourist site.

Thousands of coins have been wedged into joints by tourists in the past decades "as a token of their love or luck" said Cliff Henry, the site's Nature Engagement Officer. Some 40,000 columns mark the causeway, Northern Ireland's first UNESCO World Heritage Site.

Geologists say the natural phenomenon was created by an outpouring of basalt lava 60 million years ago. Legend has it that the causeway was formed by Irish giant Finn McCool. In recent decades, visitors have pushed thousands of coins into fissures in the rocks. Signs are now in place around the site appealing to tourists to "leave no trace".
