The Metroon served two functions; it was both a sanctuary of the Mother of the Gods and the archive building of the city, a repository of official records (Fig. 19). The present remains date to the mid-2nd century B.C. and overlie traces of earlier public buildings, including the Old Bouleuterion. The Hellenistic building had four rooms set side-by-side, united by a facade of fourteen Ionic columns. Except for a small stretch of steps at the south, all that remains are the reddish conglomerate foundations below the floor level of the building; the exact disposition of the records and the location of the statue of the Mother by the sculptor Agorakritos (cf. Fig. 20), seen by Pausanias, are unclear.
