Are getting cleaned up for the tourists (and in front of them);
The Caryatid statues, which until the late 1970s propped up a section of the Erechtheion Temple on the Acropolis, are being meticulously cleansed of grime inside the museum where they're now housed.
Three goggle-wearing conservators zap away dirt from the marble maidens with custom-designed lasers, as tourists watch the operation on monitors. The restoration work is surrounded by a white fabric screen to protect visitors from laser beams, which can cause permanent eye injury.
....The Erechtheion Temple was sacred to the gods Athena and Poseidon, and associated with the first kings of Athens. In later times, it served as a church, a Frankish palace and a Turkish harem.
What's old is new again.
