The Temple of Olympian Zeus at the end of Adrianou (to the south east of the Akropolis)

This temple was the largest in ancient Greece, and also took the longest to build. It was begun in the 6th century BC but not completed until AD 130 ! Although dedicated to Zeus, the Roman emperor Hadrian got in on the act by having a cult statue in his image as well! Most of its 104 Corinthian columns have gone but a group of thirteen remain standing
