The oldest Greek temple in Italy, lost to the ages

Today, the most significant remnants of Paestum's Greek past are its temples, including the Temple of Hera I. This temple is peripteral, with 9×18 external columns on a three-step stylobate. It stands out as the only temple in Italy with a naos (central room) divided by columns, a unique architectural feature. All the peristyle's 50 columns, including the architraves, have survived, some still bearing a floral decorative band beneath the echinus, the round part of a Doric column. The three columns in the pronaos are still in situ, along with the antae (pilasters). However, only the foundations of the external walls of the naos can be seen, as the walls have mostly disappeared, and the frieze has completely vanished.
