From ANA:

The transfer of the first of five caryatids from the old Acropolis museum to the New Acropolis Museum in Makrygianni began on Saturday at 11:00 in the morning, using the three-crane relay system set up to carry the priceless antiquities down the hill via the Theatre of Dionysus.

The caryatid - a sculpted female form that serves as an architectural support for entablature in the place of a pillar - will be placed on the first level of the new museum in an internal "porch" that visitors will see when they first climb up the grand stair at the entrance. There were originally six caryatids on the Athens Acropolis that supported the porch of the Erechtheion Temple, where they have now been replaced by replicas. The best preserved of the six statues was taken by Lord Elgin in the 18th century and is now held at the British Museum, while the remaining five originals have been on display at the Acropolis Museum.
