I am not a big museum fan so in my opinion the best part of the museum is the movie on the 3rd floor that provides the history of the Parthenon and how it was built. There is a 3D movie that shows in the morning that is supposed to be even better. As many have commented, the museum is air conditioned which is a welcome relief from the heat. The displays are pretty sterile and most of the pieces have been "reconstructed" and only are partially original stones but I guess that is to be expected when something is constructed B.C. Lots of cute shops on the walkway outside the museum. This is the best area to buy high quality replicas of original pieces.
