The Temple of Olympian Zeus is a colossal ruined temple in the centre of Athens. Construction began in the 6th century BC during the rule of the Athenian tyrants. The temple fell into disuse after being pillaged in a barbarian invasion in the 3rd century AD. Designed by the architects Antistates, Callaeschrus, Antimachides and Porinus, the Temple of Olympian Zeus was intended to be built of local limestone in the Doric style on a colossal platform measuring 41 metres by 108 metres feet. It was built in several periods, so the styles changes during the time. About two hundred years afterwards, king Antiochus, having agreed to supply the money for the work, a Roman citizen, named Cossutius, designed the further temple. It was destroyed by an earthquake in the middle Age and it was used after that as a stone pit.
