The Treasury of the Athenians, one of the finest examples of Late Archaic architecture, was erected at the beginning of the fifth century BC with a tithe of the spoils of the Battle of Marathon, part of which were displayed inside.
It was a Parian marble temple built in the Doric order. The 30 metopes of the frieze depicted the battle between the Greeks and the Amazons, the Feats of Theseus and the Labours of Herakles.
