Second Temple of Hera in Paestum

The Temple of Hera II (also erroneously called the Temple of Neptune or of Poseidon), is a Greek temple of Magna Graecia in Paestum, Campania, Italy. It was built in the Doric order around 460–450 BC, just north of the first Hera Temple of around 550–525 BC. The name "Temple of Neptune" is a misnomer from the 18th century, it is now thought it was actually dedicated to the goddess Hera, although it is possible that Poseidon (Neptune to the Romans) was also a dedicatee. A. W. Lawrence described it as "the best preserved of all Greek temples". It was listed as a UNESCO World Heritage Site in 1998. The Temple is located at 40.41982° N, 15.005695° E.
