The ancient city of Korykos extends east-west alongside the highway at a distance of 65 km from Mersin and 25 km from Silifke. It sits on the slopes of the mountain where it reaches the coast. As the mountain approaches the sea, two small bays are formed. The city lies alongside northeast and southwest axis reaching Elaiussa-Sebaste at the east and Hell-Heaven Caves at the west. It is surrounded by a natural harbor, where it has been always settled around in all periods. Remains of the ancient city are spread through 113.4 ha area reaching to the northeast of modern Kızkalesi settlement and including the fullest extent of the Necropolis valley at the west and lying 2 km alongside the coast to the east.
