The Parthenon Gallery, Acropolis Museum

The Museum's exhibition culminates in the third-floor gallery, which has been specially designed to accommodate the sculptures of the Parthenon.
The space is arranged in the form of a glass-walled chamber that wraps around a rectangular core whose orientation and dimensions match those of the Parthenon's original cella.
The construction of Parthenon started in 447 BC and was completed in 438 BC, although decoration of the building continued until 432 BC.
It is the most important surviving building of Classical Greece, generally considered the zenith of the Doric order.
