This room displays the Sphinx of Naxos and the friezes of the Siphnian Treasury.
The parts of the treasury displayed include one of the two Korae, i.e. the elegant female figures supporting the vestibule of the treasury, one of the capitals and parts of the frieze.
The eastern part of the frieze presents scenes related to the Trojan war, such as the convention of the gods, a battle scene in front of Troy (eastern frieze), a Gigantomachy (northern frieze), the judgement of Paris (western frieze) and the abduction of a woman (southern frieze), identified either with the abduction of Hippodameia by Pelops or with that of the daughters of Leukippos by the Dioskouroi.
The sculptures of the pediment of the treasury are also extant, depicting the fief between Hercules and Apollo for the possession of the Delphic tripod.

The most impressive exhibit, however, is the Sphinx.
It is an enormous statue which crowned an ionic column and capital, totaling 12 meters in height.
The column stood close to the Halos.
The Sphinx was dedicated by the city of Naxos, a wealthy island of the Aegean in its prime time, i.e. between 575 and 560 BC.
An inscription at the base of the column renews the right of "promanteia" for Naxos in the 4th century BC.
