CHRISTOPHER LIVESAY:

In fact, the Acropolis Museum was built in part as a response to the British Museum's claim that Greece did not have a proper place to display the sculptures. The glass and steel structure has a dramatic view of the Acropolis, so while you're observing the art you can see the actual Parthenon. The third floor is set up just like the Parthenon, with the same proportions. These friezes, from the west side of the temple, are nearly all original. On the other three sides, there are some originals but also a lot of gaps, as well as white plaster copies of the friezes and statues now in Britain.
