Wikipedia: The Temple of Olympian Zeus (Greek: Ναός του Ολυμπίου Διός or Naos tou Olimpiou Dios) is a temple in Athens. Although begun in the 6th century BC, it was not completed until the reign of the Emperor Hadrian in the 2nd century AD. In the Hellenistic and Roman periods it was the largest temple in Greece. The temple is located about 500 m south-east of the Acropolis, and about 700 m south of the centre of Athens, Syntagma Square.
