Didim, known for its deep historical heritage, is home to the ancient city of Priene, one of the most significant settlements of antiquity. Located approximately 20 kilometers from the town center, Priene is recognized as one of the twelve major Ionian cities established in the Aegean region. Built on a hillside, the city is admired for its well-planned layout and advanced urban design.

Dating back to the 6th century BC, Priene features remarkable structures such as the acropolis, the Temple of Athena, an ancient theater, and various sanctuaries. Most of the artifacts uncovered during excavations, mainly from the Hellenistic and Roman periods, are currently exhibited at the Istanbul Archaeology Museum. Today, Priene remains an outstanding destination for history and archaeology enthusiasts.
