Several years ago, a new airport was opened near Athens, the International Airport Eleftherios Venizelos, named after Greece’s leading statesman in the first half of the twentieth century. It has a small museum, which is quite interesting, as it documents the rural landscape east of Athens. You will find a beautiful model of a Neolithic settlement, but also finds from the Archaic, Classical, Hellenistic, Roman, and Byzantine ages. Nothing is really unique, but the objects are fine and they are well explained.
Next to it is a small exhibition on Eleftherios Venizelos; you can also see a movie about the new Acropolis Museum, both of which I found less interesting, but still preferred to passing the customs and spending time in the shopping mall.
