When and where was the statue of Zeus built?

Definition: The Athenian sculptor Pheidias (Phidias) is considered the greatest of the classical sculptors, so in 440 B.C., when it was decided that Zeus should preside via statue at the Olympic games, at Olympia*, those responsible for honoring the king of the gods commissioned Pheidias. The ivory and gold-covered statue of Zeus that Pheidias crafted sat in a Doric temple built c. 450 B.C. by the architect Libon.
