BUSHMILLS, United Kingdom: 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,” says Cliff Henry, the site’s Nature Engagement Officer. However, the coins rapidly corrode and expand, causing the rock to flake and leaving rust-coloured streaks, Henry tells AFP. – Peter Murphy/AFPTV/AFP
