The new Acropolis Museum opened in 2007. The facility is gorgeous. Walking through the 150,000 square feet of exhibition space is time consuming but you will be fascinated with every step. Among the highlights in the permanent collection are five of the original caryatids (woman columns) from the Erechtheion. You will also admire sections of the 524 foot frieze from inside the Parthenon. The high-relief marble panels were sculpted between 443 and 437 BC. A common image was horsemen. Each figure displays incredible anatomical details.
