Temple of Athena Pronaia, Ancient Greek temple in Delphi, Greece.

The Temple of Athena Pronaia stands in the sanctuary of Marmaria, about 1,500 m east of and below the temple of Apollo, on the road pilgrims took to Delphi. Three temples were built in succession: temple A of grey porous stone in the 7th century BC, temple B of the same stone around 510 BC, and a limestone temple C of about 360 BC. Beside them is the Tholos, a circular building 13.50 m across with twenty Doric columns.

Three temples stood here in succession. Temple A, of grey porous stone, was built in the 7th century BC and destroyed in the first half of the 6th, possibly by an earthquake. Temple B replaced it around 510 BC, probably under the Alcmaeonids' building programme; fifteen of its columns still stood in 1905 until a rockfall brought them down. Temple C, of limestone, followed around 360 BC.

The name Pronaia means "the one before", because this sanctuary was the first a pilgrim walking from the east reached before the temple of Apollo. Pausanias records that the Massiliots, a colony of Phokaia, dedicated a bronze image of Athena in the fore-temple, larger than the one inside, and that Kroisos of Lydia gave a gold shield said to have been stolen by Philomelos.

The site is accessible through the main Delphi complex and can be reached on foot from there. Visitors should wear comfortable shoes since the terrain is hilly and some areas require walking across uneven ground.

The Tholos of Delphi in this sanctuary had a floor of dark Eleusinian limestone with a central circle of white marble, and its walls rested on a black or blue stone course. Pentelic marble was used for the main structure, creating a deliberate polychrome effect.
