The Sanctuary of Athena Pronea is the site of the 4th-century-BC tholos (rotunda). This much-photographed spot is often wrongly interpreted by tourists as the place the Pythia delivered her pronouncements. The graceful circular structure comprised 20 columns on a three-stepped podium; three of its columns were re-erected in the 1940s. The white portions of each column are the original marble; the darker portions are new material.
To its west, the foundations of the Temple of Athena Pronea are all that remain of a rectangular structure that was heavily damaged by the same rockslides and earthquake that levelled much of the tholos .
