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

The First Temple of Hera (Paestum)—also known as Temple of Hera I and the Basilica—is an archaic Doric order Greek temple in the ruins of the ancient city of Paestum, Italy. This Doric temple is considered one of the oldest Greek temples in Italy and is known for its distinctive architectural features. It was built around 550–525 BCE, within a century of the city's establishment by Greek colonists from Sybaris, who named the city Poseidonia.
