The Athenian Treasury at Delphi was constructed by the Athenians to house dedications and votive offerings made by their city and citizens to the sanctuary of Apollo. The entire treasury including its sculptural decoration is built of Parian marble. The date of construction is disputed, and scholarly opinions range from 510 to 480 BCE. It is located directly below the Temple of Apollo along the Sacred Way for all visitors to view the Athenian treasury on the way up to the sanctuary.

Delphi, in legend previously called Pytho (Πυθώ), was an ancient sacred precinct and the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The ancient Greeks considered the centre of the world to be in Delphi, marked by the stone monument known as the Omphalos of Delphi (navel).
