Didyma is located 75 km south of Kusadasi. As a logical continuation, after Priene and Miletos, one goes to Didyma, a famous temple for its oracles. This temple dedicated to Apollo was the richest and biggest of the Ionian temples on Anatolian soil. It was to cover such a vast area, that its construction lasted more than 150-200 years and yet it was planned to be without ceiling. Again after the “Ionian Rebellion”, it was to Alexander the Great to order its restoration. On the ruins of the VIth century BC temple, a church was built during the Byzantine period. Though the ruins one can see today, are of pre-Christian age.
