Didyma

Didyma (; ) was an ancient Greek sanctuary on the coast of Ionia in the domain of the famous city of Miletus. Apollo was the main deity of the sanctuary (also called the Didymaion), and it included temples to both Apollo and his twin sister, Artemis; other deities were also honoured there. Didyma was known in antiquity for its famed oracle of Apollo, situated within the god's temple. The remains of this Hellenistic temple are among the best-preserved from classical antiquity. Other buildings from the sanctuary included a Greek theatre and the Hellenistic temple of Artemis.

==Geography== thumb|350px|Map of the area around ancient Didyma The ruins of Didyma are located a short distance to the northwest of modern Didim in Aydın Province, Turkey, whose name is derived from the ruins. It sits on a headland that in antiquity formed the Milesian Peninsula. Didyma was the largest and most significant sanctuary on the territory of the great classical city Miletus. The natural connection between Miletus and Didyma was by way of ship. But during antiquity the sediments from the Meander River silted up the harbour of Miletus. A slow process which eventually meant that the nearby Latmian Gulf developed from a bay into a lake (today Bafa Gölü).
