The Treasury of the Cyreneans was probably the last treasury to have been built within the sanctuary of Apollo. It dates to 334-322 B.C. and it was built right next to the eastern part of the precinct, on a crepis consisting of three steps and made of limestone. It was made of marble, both from Paros and from the Pentelikon, distyle in antis with a vestibule, a cella and an elevation of the Doric order.  In the interior of the antae were attached semi-columns. The roof was made of marble and its sima bore gargoyles in tubular and leonine forms. On the north anta is engaved an insciption offering the promanteia to the Cyrenaeans on behalf of the city of Delphi, as a reward for the wheat they had offered during a famine.  In front of the treasury, which was oriented towards the temple of Apollo, there was a small square, whereas to the south there has been discovered the foundation of a building which was formerly identified as the prytaneion of Delphi, but which probably had another use, judging from its size.
