For years, visitors left coins for luck in Giant’s Causeway’s ancient rocks. Years later, more than 10,000 coins have been removed to protect the World Heritage Site

• Coins were pushed into gaps between the site’s distinctive basalt columns, sometimes as a gesture of luck or affection.
• What might have seemed harmless began to leave a physical mark on the rocks.
