The settlement in the Inişdibi area, where the Idyma fortress is located, has a continuous history of habitation dating back to the 7th century BC. It is believed that the fortress itself — one of the largest and most important Byzantine monuments in the region — was built in the 12th century AD to protect against Turkish raids.
During ongoing excavations beneath the walls, even older structures have been discovered. It has also been found that the fortress was used in subsequent Ottoman periods. A sarcophagus from the Hellenistic period and rock tombs from the classical period were found in the area near the fortress.
The fortress offers a stunning view of the bay,
Azmak River, and Akyaka.
Research on the fortress, as well as related finds — basilicas, mosaics, and other objects — is still ongoing, and Akyaka is gradually preparing for the development of historical tourism.
