Room 3 is dominated by the Kouroi of Delphi, archaic male statues known also as Cleobis and Biton, which were produced at Argos between 610 and 580 BC.
It also contains the metopes of the Treasury of the Sicyonians.

The latter include four metopes made of yellowish porous stone from Sicyon, coming from the so-called "monopteros".
They depict scenes from the Argonautic expedition, a scene from the myth of the Dioskouroi abducting the oxen of Arkadias aided by their cousins, Idas and Lyngeus, some scenes from the hunt of the Calydonian boar and, finally, the scene of the abduction of Europe by Zeus transformed into a bull.
 Some bronze figurines of the 6th century BC are also displayed in the same room, of which notable is a figurine of Apollo, made by a Laconian workshop.
On one of the cases fastened against the wall is displayed a bronze tile depicting a scene from the Odyssey: a man, possibly Ulysses, tied under the belly of a ram is possibly escaping from the cave of Polyphemus; another tile depicts Hercules carrying the Erymanthian boar to king Eurystheus, who hides in a jar, terrified.
Finally, simae from two archaic treasuries are also displayed; they are made of terracotta and are decorated with rosettes and spiral motifs.
