Temple of Hera II

The Temple of Hera II (sometimes called the Temple of Neptune), is a Greek temple in Paestum, Campania, Italy. The name Temple of Neptune is a misnomer from the 18th century, even though, it was actually dedicated to the goddess Hera. It is part of the UNESCO World Heritage site.

The second temple to Hera, the nearby Temple of Hera (also called of Neptune), was built around 460–450 BC. It has been variously thought of as a temple dedicated to Poseidon. The Temple of Hera II has nothing in common with the first temple, reason being for its symmetrical style for its columns. Also every column does not have a normal 20 flutes on each column but it has 24 flutes. The Temple of Hera II also has a wider column and a smaller spacing for the placing of the columns. The temple was also found to be used to worship more than just Hera but also Zeus and another unknown god. There are visible on the east side the remains of two altars, one large and one smaller. The smaller one is a Roman addition, built when they cut through the larger one to build a road to the forum. It is also possible that the temple was originally dedicated to both Hera and Poseidon; some offertory statues found around the larger altar are thought to demonstrate this identification.
