Visitors to the Giant's Causeway have been urged to stop wedging coins into the gaps between the famous stones as they are damaging the site.
Coins squeezed into the gaps in the basalt columns of the tourist attraction in north Antrim eventually rust and expand, putting pressure on the surrounding rock, staining it and causing it to crumble, the National Trust said.
Scores of coins left in the cracks are being removed by the trust, an operation it estimates will cost more than £30,000.
Dr Cliff Henry, from the National Trust, said visitors "really love and cherish the Giant's Causeway, and many form deep personal connections to this special landscape".
