The treasury was possibly built as a token of gratitude for a large endowment of wheat offered to Delphi's inhabitants during a lean period.

It was constructed at the eastern part of the precinct, supported by a base (crepis) made of limestone and consisting of three steps.

The elevation of the treasury was made of two kinds of marble with provenance from Paros and Mount Pentelikon.

The building was covered by a marble roof, the sima of which was decorated with gargoyles in alternating forms (lion heads and simple tubes).

[2] An inscription on the north anta mentions that the Cyreneans were accorded the promanteia by the city of Delphi, as a sign of gratitude for a heavy load of wheat that the former offered the latter during a period of famine.
