No permanent damage to Trevi Fountain says Rome mayor

(see related) (ANSA) - ROME, MAY 21 - Climate activists who poured black liquid made from diluted vegetable charcoal into the Trevi Fountain have not caused permanent damage, Rome Mayor Roberto Gualtieri said on Sunday.
    "Fortunately, the initial assessment is that there should be no permanent damage because the black paint settled on the waterproofing, not on the marble," said Gualtieri, adding that it should be possible to remove it.
    "The risk is when it goes on the marble, which is porous," he explained. (ANSA).
