The Parthenon is Built

The Parthenon was constructed between 447 and 432 BCE on the Acropolis of Athens, dedicated to Athena. Directed by Phidias with architects Ictinus and Callicrates, it used optical illusions — slightly curved columns and floors — to appear perfectly straight. The thing cost roughly 469 silver talents (hundreds of millions in today's money). It's still standing and still goes hard. The Elgin Marbles in the British Museum are from this building, and Greece wants them back.
