They’re some of Greece’s most celebrated beauties. And after nearly 2,500 years, it’s perhaps only fitting that they’re getting a face-lift. The Caryatid statues, which until the late ’70s propped up a section of the Erechtheion Temple on the Acropolis, are being meticulously cleansed of grime inside the Athens museum where they’re now housed.

But there’s the additional value of offering tourists the spectacle of restoring some of the greatest glories of the ancient world. “We want to offer visitors a backstage peek,” he said.
