Located on the south side of the Erechtheion, an Acropolis temple dedicated to Poseidon and Athena, the Porch of the Maidens faces the Parthenon.  The Porch of the Maidens is bounded by six caryatids, columns shaped like women.  The caryatids on the Erechtheion are replicas.

Five of the six original marble caryatids reside in the Acropolis Museum in Athens where they are being restored and protected.  The sixth caryatid is displayed at the British Museum.  Greece wants to reunite all six maidens in Athens.
