There were several treasuries in Delphi. The small yet elaborate structures were constructed by different Greek states. The buildings safeguarded valuables for temple offerings plus housed materials used by visiting embassies. The most famous example is the Athenian Treasury. The marble Doric structure was built around 500 BC. Among the 40 metopes (square panels below the pediment) are bas-reliefs of Herakles (Hercules) and Theseus (a mythical king and Athenian hero). The carvings celebrate Athens’ victory in 490 BC over the Persians in the Battle of Marathon. The Athenian Treasury you see at a bend in the Sacred Way is a replica. The original is inside the Delphi Archaeological Museum.
