The temple known as the Temple of Athena or Temple of Ceres (c. 500 BCE), is located in the northern part of Poseidonia-Paestum, in the sector between the north-south and east-west plateiai (main roads with larger size). The Temple dominated and still dominates the entire archaeological area of Paestum and it was built in a transitional style between Ionic and early Doric, with large blocks of travertine and bordered by pine trees.
Is the only temple whose attribution is certain on the basis of the numerous terracotta statuettes depicting this deity recovered here, along with some inscriptions naming Athena The temple must have replaced an earlier one whose existence is evidenced by architectural decoration dated to 580–560 BCE . This was particularly important in city life and had an interior part higher than the surrounding colonnade that could be accessed through a richly decorated antechamber.
The discovery of the architectural antefix of the big temple of 580–560 BCE within the layer of destruction and rearrangement of the temenos (sacred area) at the end of the sixth century BCE may be regarded as evidence of a sudden and traumatic event that affected the sanctuary, such as a fire. These data were recently confirmed by a study of the metal objects from the temple, nowadays held at the Paestum Museum, which shows evident traces of fire.
It is likely that after this event the sanctuary was rebuilt and reorganized, along with a large part of the archaic city.
The temple has dark sandstone in its upper areas. There are several sandstone ridges that are incorporated in the delta of the Sara River, each of which formed as a shoreline that had been left behind as the Sara River delta grew progressively seaward during the interval of the Pleistocene (the Ice Age) to the present.
The temple with a porch of 34 fluted columns (6 on the short sides and 13 on the long sides), was transformed into a Christian church during the High Middle Ages, as indicated by three Christian tombs discovered in the floor.
The excavations, which freed the temple from the rest of a medieval village that was built next to it, brought to light a sacrificial altar and numerous remains of Greek buildings, some older than the temple.
