Ayasuluk Fortress

Ayasuluk Fortress (also known as Selçuk Fortress) stands atop a high hill. It was built by the Byzantines in the 6th century and later fortified and rebuilt by the Turks after their conquest of the region in the 12th century. The need for such a powerful citadel arose due to the retreat of the Aegean Sea several kilometers eastward in this region.
