First Temple of Hera (also called "The Basilica")

The First Temple of Hera at Paestum, also called the Basilica, is an archaic Doric Greek temple among the ruins of the ancient city of Paestum in Italy. Built around 550 to 525 BCE, it is one of the oldest Greek temples in Italy. Its construction came within a century of the city’s founding by Greek colonists from Sybaris, who originally named it Poseidonia. The temple is notable for its distinctive Doric features, including a pronounced entasis and a nine-column facade, an unusual configuration. Its survival through millennia offers a rare, tangible link to the early Greek presence in southern Italy.
